Meta employment-ad targeting and delivery optimization

What this models

This example runs on the Platform-class employment-ad delivery allocation network: 10 components and 25 pathways between them. Every context in the Lab is a stylized model, never a reconstruction of any actual deployment, and each assumption behind it carries a provenance label.

Evidence base: 13 published baseline. In the Lab, the shaded evidence band behind each headline readout draws its width from the least-established class below.

• baseline

  THE POSITION IS THE POINT. This deployment allocates attention, not applicants: it decides which users inside an advertiser's eligible audience receive impressions of a job ad, so it acts before anyone applies. That is why this network has no applicant record, no adverse-action store, no recruiter class and no per-decision human step - the people it does not reach never apply anywhere and generate no data of any kind. Every screening board in this domain draws the opposite shape, and the difference is the deployment's, not a modelling choice.

• baseline

  TWO MODELS, BECAUSE THE RECORD DOCUMENTS TWO. The allocator is the production system the peer-reviewed audits measured. The variance controller is a second, later system a federal settlement required, with its own measurement stack (sampled eligible-audience demographics, surname-and-geography race estimation, differential-privacy noise on the aggregates) and its own reporting obligations. Drawing them as one model would collapse the remedy into the thing it was built to measure.

• baseline

  BASELINES FOR THE REINFORCING PATHWAYS mirror the PAN org's evidence-derived edge rates as rungs: 0.50 and above reads 3, 0.30 to 0.49 reads 2, 0.06 to 0.29 reads 1, and a pathway the record documents as not performed reads 0. The two widest rungs are the read and the write halves of one loop - the allocator learning from historical engagement and writing each delivery outcome back into what it learns from next - which is the mechanism the 2019 study describes and the pleading is about.

• baseline

  THE CHECK RUNGS ARE DERIVED ONE AT A TIME, NOT MAPPED. One fact governs all of them: no check in this record is verified against employment ads. The compliance-reporting cycle reads 1 - a real four-monthly cadence with a court behind it and five published reports, every one of them covering housing ads, the last covering a period ending in August 2024. The variance check on delivery reads 1 - the operator reports the same controller running on US employment and credit ads since October 2023, and the record carries no metric, no employment figure and no third-party verification for that ad category. The audit finding reaching employers reads 1 - two peer-reviewed studies exist and are public, and the pathway asks an advertiser to read academic literature about a campaign it cannot inspect. The administrative determination reads 0 and the reconciliation of published figures against the platform's own delivery data reads 0, both because the record documents them as not performed. PAN's ordering survives: the verifier hop sits above the charge hop on both sides of the derivation.

• baseline

  THE SECOND LEAK CHANNEL IS DRAWN AS ITS OWN PATHWAY. The 2019 study documents budget and market effects as a skew channel separate from the relevance predictions: under a budget constraint the demographics that cost less to reach take more of the impressions. The PAN file folds that into an attribute of the delivery-history store; this network draws it as the advertiser's own bid and budget entering the auction, because it is the pathway the March 2019 settlements acted on when they took gender, age, affinity and postal codes out of what an advertiser may specify, and because it is why a neutral specification does not settle the question.

• baseline

  THE HANDOFF EDGE CARRIES THE STRUCTURAL ARGUMENT. The eligible-audience specification becomes the population the allocator works within, and the record's shape is that each remedy landed one layer above the measured failure: the March 2019 settlements restricted what an advertiser may ask for, and weeks later a peer-reviewed study measured skew surviving identical neutral targeting at the delivery stage. The handoff is drawn at the same rung as the other record-side transfers rather than as the widest thing on the board, because the layer mismatch is a fact about where two well-documented instruments sit, not an assertion about magnitude.

• baseline

  DEMAND 3 AND CAPACITY 1. Demand from the documented base: more than 30,000 US job ads published daily, roughly 239 million US users, and an allocation decision taken for every impression, with no queue and no per-case desk anywhere in the deployment. Capacity 1 because no source documents a human allocation function at this scale, and the human-directed alternative the record does document is the pre-2019 arrangement in which advertisers chose audiences by demographic targeting themselves - the arrangement that drew the EEOC's reasonable-cause determinations against seven employers, announced 25 September 2019. It reads 1 rather than 0 because broad delivery inside an eligible audience is a real alternative and the direction the fifteen-mile floor and the postal-code ban push toward.

• baseline

  ONE PATHWAY CARRIES THE PRIVACY FLAG. The allocator's read of the engagement and delivery history is the flow that carries personal data at population scale - stated age and gender, inferred interests and engagement histories on hundreds of millions of people - and it is the flow whose use in delivery the pending charge alleges and the operator disputes. The controller's read is deliberately not flagged: its measurement stack is aggregate, adds differential-privacy noise and keeps no individual-level race data, and that minimisation is documented rather than assumed.

• baseline

  THE TRANSPARENCY ASYMMETRY IS A COMPONENT, NOT A CAVEAT. Per-ad demographic delivery tables are published for ads classified as issues, elections or politics, and that classification decides publication; employment-ad delivery demographics sit outside it. The board draws the consequence three times over: the publication pathway out of the allocator sits at the floor rung, the pathway returning delivery information to the employer sits at the floor rung, and the reconciliation of published figures against the platform's own data reads 0. The pending charge's own evidence exists because some job ads carried the political classification.

• baseline

  THE DELIVERY-LAYER DISCRIMINATION CLAIM IS A PLEADING AND IS DRAWN AS ONE. Asserted flatly on this network: the 2019 settlement terms and their implementation, the June 2022 settlement's terms and the $115,054 civil penalty, the termination of the special ad audience tool, the controller's housing-ad compliance metrics and the reviewer's verified results, and the peer-reviewed finding that identically targeted job ads were delivered to skewed audiences in the 2019-to-2021 era. Attributed to the EEOC: that seven employers violated federal law through their own job-ad targeting. Carried in the allegation register only: that the delivery algorithm relies on gender and age or discriminates in employment. Meta disputes the charge and says addressing fairness in ads is an industry-wide challenge; no tribunal has found the delivery algorithm unlawful in employment.

• baseline

  THE HOUSING RECORD SUPPLIES THE REMEDIAL TECHNOLOGY, NEVER AN EMPLOYMENT FINDING. The June 2022 federal settlement was brought under fair-housing law; its metrics, its four-monthly reporting, its independent reviewer and its verified results all cover housing ads. This network carries that record because it is where the delivery-layer control and its numbers come from, and because the gap between it and employment ads is the space the pending charge occupies. Every surface that carries a verified figure says which ad category it belongs to.

• baseline

  COARSENED AT RE-DERIVATION, AND WHERE THE SIX FACTS WENT. This board was re-drawn at the coarsest granularity that still distinguishes every mechanism the record documents, and six pathways the first derivation drew on their own are now carried by a survivor, because each was a second drawing of a flow already running between the same pair of things. The controller's read of the portal specification sits inside its read of the delivery data, which is where the record says the sampled eligible-audience distribution is read from. The allocator's visibility to the operator sits inside the operator's read of its own delivery data. The operator's read of its own controller sits inside the writes by which it builds and extends that controller, which is where the rollout is reported. What the portal shows an employer sits inside the employer's composing write. The delivery data's route into the published library sits inside the allocator's, because one classification rule, applied per ad, decides publication on both. And the charge's filings on the public record sit inside the pathway that carries its exhibits off it. Ten components, eleven pathway kinds, five checks, two documented absences and every surviving rung are unchanged, and no documented fact left the page. The PAN entry draws all six separately; the divergence is a drawing granularity on this side and is recorded here, not in that file, which this programme never edits.

• baseline

  SERVED PEOPLE ARE A BOUNDARY, NOT A DYNAMIC. Nothing on this diagram computes an outcome for any job seeker: no application, no hire, no wage and no score over a person is authored anywhere. The record's per-ad delivery percentages are recorded external observations from the charge's exhibits, with their own single-ad denominators, and they are quoted as documented examples from a corpus of more than seventy-five postings rather than as platform rates. The Lab propagates institutions.

What this example does not show

• The claim that this delivery algorithm discriminates in employment is a PLEADING. The class charge filed on 1 December 2022 and joined on 19 December 2023 alleges it, in the disparate-treatment, disparate-impact, advertising-discrimination and employment-agency registers; its per-ad delivery figures come from the platform's own public tables and are consistent with the peer-reviewed literature; and Meta disputes the charge, saying that addressing fairness in ads is an industry-wide challenge. No tribunal has found this delivery algorithm unlawful in employment, counsel's case page listed the charge as pending when it was read on 28 August 2026, and no public determination has issued.
• The EEOC reasonable-cause determinations announced on 25 September 2019 ran against seven EMPLOYERS for their own targeting choices, not against the platform and not against the delivery algorithm. Reasonable cause is an administrative finding rather than a court judgment, the conciliations that followed have no public outcomes, and the verified release does not date the determinations' issuance - the September 25 date is the announcement's. The restricted portal came from the private March 2019 settlements, not from those findings, which produced no platform remedy.
• The June 2022 federal settlement is HOUSING-anchored: a fair-housing complaint with a fair-housing lineage, settled without any admission of liability. It is carried here for the remedial technology - the controller's mechanism, its court-agreed metrics and its independent verification - and never as an employment finding. The extension of that controller to US employment and credit ads is reported by the operator in its own newsroom, with no published metrics and no third-party verification. The court's oversight term expired on 27 June 2026, the last published verification covers 1 May to 31 August 2024, the government case page was last updated on 21 January 2025, and the post-expiry status of those obligations is undocumented in public sources as of 28 August 2026 - expired, with no public disposition located, which is not the same as terminated or extended.
• The delivery percentages are per-ad snapshots from a pleaded corpus of more than seventy-five postings, quoted as documented examples and never as platform rates: a commercial-driving ad at 94 percent men and 5 percent women in the charge. The peer-reviewed audits measured the platform in 2019 and 2021, before the controller existed even for housing ads, so their magnitudes do not transfer to post-2023 delivery without saying so. The 2025 disparate-impact developments are known from an executive order text and legal-press reporting of an internal memorandum; the charge also pleads intentional discrimination, which that directive reportedly exempts, so the charge is neither shown closed nor shown unaffected. The roughly five million dollars often attached to the March 2019 settlements comes from contemporaneous press, not from the joint statement, which discloses no monetary terms.
• Job seekers are not modeled. Whether a person saw a posting, applied, was interviewed or was hired is a boundary quantity recorded in the case file; the Lab propagates institutional dynamics through the operator network and computes no outcome for any person. The screened-out population is, by the deployment's own structure, unmeasured everywhere: it generates no application, no rejection and no record, which is why this case has evidence about ads and none about the people the ads did not reach.

Sources and evidence

What this example rests on, claim by claim. Every entry resolves to the same ledger the Evidence Registry publishes.

• Meta Platforms' advertising system decides, for every job ad, which users inside the advertiser's eligible audience actually receive impressions, optimising predicted relevance and engagement against auction economics — so the allocation runs before anyone applies and the people it does not reach generate no application, no rejection, and no adverse-action record anywhere. The platform's own published data, as recorded in the December 2022 class charge and the December 2023 joinder release, gives the scale: roughly 239 million US Facebook users, more than 30,000 US job ads published daily, women 54 percent of users interested in job hunting and people 55 and over more than 28 percent of them. The governance record runs on two layers that do not coincide: a restricted advertiser portal created by private settlement in March 2019, and a delivery-optimisation stage that independent peer-reviewed audits measured weeks later.

• On 19 March 2019 Facebook settled five coordinated legal actions — brought by the National Fair Housing Alliance and three regional fair-housing organizations with Emery Celli Brinckerhoff & Abady LLP, the Communications Workers of America, Outten & Golden LLP, the American Civil Liberties Union, and individual plaintiffs — by agreeing to structural platform changes recorded in a joint statement the company co-signed: housing, employment, and credit ads confined to a separate restricted portal; no gender, age, or multicultural-affinity targeting; a fifteen-mile minimum geographic radius and no postal-code targeting; Lookalike Audiences for those ads stripped of gender, age, religion, postal-code, and group-membership inputs; detection and rerouting of covered ads created outside the portal; advertiser anti-discrimination certification; plaintiff testing rights and regular implementation meetings; and a commitment to engage researchers on algorithmic bias, with implementation by 30 September 2019. The joint statement discloses no monetary terms; the roughly five-million-dollar figure attached to these settlements comes from contemporaneous press reporting rather than from the document.

• In April 2019, weeks after the settlements took effect, Ali, Sapiezynski, Bogen, Korolova, Mislove, and Rieke published a peer-reviewed study (CSCW 2019) showing that paired employment and housing ads carrying identical neutral targeting were delivered to strongly gender- and race-skewed audiences by the delivery stage itself, driven by the platform's own relevance predictions plus budget and market effects — with the budget channel operating independently of the content channel, because under a budget constraint the demographics that are cheaper to reach take more of the impressions. The method used ordinary advertiser accounts and was reproducible by outside auditors. In 2021 Imana, Korolova, and Heidemann (WWW 2021) controlled for qualification distributions by running paired ads for the same job at companies with different de facto workforce gender mixes, confirmed gender skew in Facebook's job-ad delivery that qualification differences do not justify, and found no comparable skew on LinkedIn — making the behaviour platform-specific rather than labour-market-inevitable. Both studies measured the platform in the 2019-to-2021 era, before any remedial delivery controller existed even for housing ads.

• On 21 June 2022 the United States sued Meta Platforms under the Fair Housing Act over housing-ad delivery, following a HUD Secretary-initiated complaint and charge, and on 27 June 2022 the court entered a settlement in United States v. Meta Platforms, Inc., No. 22-cv-5187 (S.D.N.Y.): Meta stopped using the Special Ad Audience tool, paid the $115,054 civil penalty that was then the statutory maximum, and agreed to build a Variance Reduction System to shrink the gap between an ad's eligible audience and its actual audience by sex and estimated race or ethnicity, under a compliance-metrics agreement of 9 January 2023, four-monthly reporting, an independent third-party reviewer, and court oversight through 27 June 2026. The system samples eligible-audience demographics, estimates race and ethnicity by Bayesian Improved Surname Geocoding at a 50 percent threshold with differential-privacy noise added to the aggregates, retains no individual-level race data, and adjusts ongoing delivery in flight. Guidehouse Inc. issued five verification reports between June 2023 and 30 October 2024 (the fifth updated 19 December 2024); in its period of 1 May to 31 August 2024, for housing ads above 1,000 impressions, 95.1 percent met the ten-percent sex-variance threshold against a 91.7 percent requirement and 85.5 percent met the ten-percent estimated race and ethnicity threshold against an 81.0 percent requirement, with the reviewer's independent recomputation matching Meta's reported coverage at a 0.0 percent difference. All of the court-supervised metrics and all published verification cover HOUSING ads. Meta reports in its own newsroom having extended the same system to US employment and credit ads by October 2023, an operator-reported extension with no published compliance metrics and no third-party verification. The court-oversight term expired on 27 June 2026; the Department of Justice case page was last updated 21 January 2025 and lists no verification report after 30 October 2024, and no public post-expiry disposition was located as of 28 August 2026.

• PLEADING, NOT A FINDING. On 1 December 2022 Real Women in Trucking filed a class charge of discrimination with the Equal Employment Opportunity Commission (No. 570-2023-00655), through Gupta Wessler PLLC and Upturn, Inc., alleging that Meta's ad-delivery algorithm discriminates by sex and age in deciding who receives job ads and pleading disparate treatment, disparate impact, the advertising-discrimination provisions, and an employment-agency theory under Title VII and the ADEA and under state and local law; the charge alleges the post-2019 era inverted the mechanism, so that where job ads were once unlawful because advertisers expressly excluded older people and women, they are alleged to violate federal law since 2020 because the delivery algorithm itself relies on gender and age to limit who sees them. Its exhibits are tables from Facebook's own public ad library for ads whose eligible audiences were all-gender and all adult ages: a commercial-driving ad shown 94 percent to men and 5 percent to women, a mechanic ad above 99 percent to men, another blue-collar ad at 1 percent women and 3 percent users 55 and over, a school administrative-assistant ad at 2 percent men and 6 percent users 55 and over, a health-facility hospitality ad at 83 percent women, and a correctional-nursing ad at 22 percent men and 18 percent users 55 and over. AARP Foundation joined the charge on 19 December 2023 on behalf of older workers, citing more than 75 job postings as the evidentiary corpus. Meta's public response is that 'Addressing fairness in ads is an industry-wide challenge,' citing collaboration with civil-rights groups, academics, and regulators. No tribunal has found Meta's delivery algorithm unlawful in employment. Counsel's live case page, accessed 28 August 2026, lists the charge as pending with no public EEOC determination. Its enforcement environment changed in 2025: the executive order of 23 April 2025, 'Restoring Equality of Opportunity and Meritocracy,' directed agencies to deprioritise disparate-impact liability, and a reported internal EEOC directive ordered disparate-impact-only charges administratively closed by 30 September 2025 with right-to-sue letters by 31 October 2025, from which charges also alleging intentional discrimination reportedly proceed on that theory alone.

• Facebook's public ad library publishes per-ad demographic delivery tables only for ads classified as 'Issues, elections or politics.' Employment ads receive no such disclosure unless they carry that classification, so neither employers nor job seekers can routinely observe the demographic composition of a job ad's delivery — and the December 2022 charge's own per-ad evidence exists precisely because some job ads were so classified, as does the corpus of more than 75 postings the AARP Foundation cited when it joined in December 2023. The consequence recorded across this case's sources is that every delivery-layer finding in the record originated outside the operator: paired-ad academic audits run on ordinary advertiser accounts, and advocate harvesting of the ad library.

• ATTRIBUTED TO THE EEOC, AND AGAINST ADVERTISERS. On 25 September 2019 the American Civil Liberties Union announced that the Equal Employment Opportunity Commission had issued reasonable-cause determinations against seven employers — Capital One, Edward Jones, Enterprise Holdings, Drive Time Auto, Nebraska Furniture Mart, Renewal by Andersen, and Sandhills Publishing — finding they unlawfully excluded women and older workers from the audiences of their Facebook job ads. The determinations form part of roughly 66 charges filed since 2018 by the Communications Workers of America, the ACLU, and Outten & Golden (56 age-only, 10 age and gender), addressed advertiser TARGETING choices rather than the platform's delivery algorithm, produced no platform remedy, and moved to conciliation with no public outcomes since. Reasonable cause is an administrative finding, not a court judgment, and the verified release does not itself date the determinations' issuance — 25 September 2019 is the date of the announcement.

Where this connects

Institutional pressures in this domain

• Workload surge — Demand outruns staffing; per-case attention shrinks and review becomes triage.
• Vendor opacity — The deploying institution cannot inspect the model, data, or update pipeline it is accountable for.
• Compliance over substance — Paper controls (sign-offs, checklists) satisfy audits while the behavior they describe erodes.
• Data & policy drift — The world, the intake process, and the rules change under a system trained on how things used to be — two mechanisms with different remedies: the statistical properties of what the system processes move (concept drift), or the mixture of inputs arriving in deployment differs from the mixture it was trained on (covariate shift).
• Reviewer bottleneck — One fixed-capacity checking stage sits between AI output and consequence; everything queues behind it.
