PolicyEngine data

How the microdata behind PolicyEngine population runs is built, calibrated, versioned, and named. For using datasets in a simulation, see the policyengine skill (this skill is about where the data comes from). For diagnosing why one score disagrees with a benchmark, see policyengine-calibration-diagnostics.

The current data stack is Microcosm (repo PolicyEngine/microcosm, local mirror ~/PolicyEngine/microcosm; read its README.md + DESIGN.md). It replaced the technique-named packages of the previous stack (microdf / microimpute / microcalibrate / L0 / policyengine-us-data), which shared no datatype and had their worst bugs at the seams between flat DataFrames.

The Microcosm architecture

Microcosm is one kernel datatype — the Frame — with packages as operators on it. It is a PEP 420 namespace (microcosm.*) shipped as independently-installable shard distributions, so an analyst doing imputation never has to install torch and vice versa. Microcosm releases pin the shards as a constellation.

Package	Import	Role	Succeeds
`microcosm-frame`	`microcosm.frame`	the kernel: `Frame`, typed weights, strata, links, weighted accounting, unit structure, the RulesEngine protocol	microdf, microunit
`microcosm-fit`	`microcosm.fit`	conditional models (weight-aware by construction)	ad-hoc imputation scripts
`microcosm-calibrate`	`microcosm.calibrate`	targets → calibrated weights (APG / L0)	microcalibrate
`microcosm-build`	`microcosm.build`	build plans, donor graphs, release gates, country build stages	one-off build drivers
`microcosm-data`	`microcosm.data`	published population registry + lazy engine loaders	country-specific data packages

Key design facts (from DESIGN.md) that change how you reason about the data:

The Frame is a weighted sampling frame of entity tables. Person + group-entity tables with explicit person_<group>_id linkage established once at assembly — no operator re-derives person↔unit attachment from a flat frame. It carries typed weights (design | importance | calibrated, one vector per weighted entity) with conservation invariants the kernel enforces (strata mass sums; no silent zeroing; no NaN/negative), and strata giving every record explicit provenance (cps_passthrough, synthetic_conditional, tail_verbatim, ...). Generation owns support (oversample where it is scarce); calibration owns representation.
The rules engine is an adapter, not a dependency. microcosm.frame.rules.RulesEngine is a Protocol (variable_entity, variable_dtype, entity_schema, materialize, export_contract, write_dataset). Today's adapter is policyengine_us; the Axiom rulespec-us adapter is written against the same protocol so the swap is a new adapter, not a migration.
microcosm-fit is weight-aware by construction — fits read the frame's typed weights; there is no unweighted default. Canonical model: regime-gated, chained quantile forests with weights materialized by weighted bootstrap.
microcosm-calibrate is the only place calibrated weights are produced. Sparse target-matrix compilation + APG / L0 pruning is the core, not an option — "generate big then prune" is the intended design (300k → 3M → 30M candidate pools pruned to a compact frame). Its longitudinal rule: one weight per trajectory (multi-period targets stack as (target, period) constraint rows over one weight vector).
Process rules are as binding as the architecture: behavioral contract tests in CI from day one (weighted fits shift draws toward the weighted truth; calibration conserves declared mass; unit assignment partitions exactly); constellation versioning (consumers pin the constellation, not git SHAs); artifacts embed a certificate of the rules-engine + package versions that produced them; stage manifests are versioned artifacts with invariant checks.

The long-run goal in DESIGN.md ("The commons") is a communal, continuously-improving synthetic population where the three contribution types are the package decomposition — records (new strata at honest weights, frame), conditional structure (fitted P(y|x) models, fit — the only way private sources contribute), and facts (targets with standard errors, calibrate — Chronicle's lane). A contribution merges iff it improves the population's score on held-out, rotated evidence without degrading a protected target family beyond tolerance.

Certified releases → policyengine bundles

Builds that pass the release gates are published to Hugging Face (policyengine/populace-us, policyengine/populace-uk-private) and referenced by name in the certified bundle manifest that ships inside the policyengine package. Verified in policyengine 4.21.0 (policyengine/data/ bundle/manifest.json):

Dataset	What	How to load
`populace_us_2024`	US default. Build J, sparse, ~57k households calibrated to tens of thousands of admin targets	resolves automatically; do not pass a raw URI
`populace_us_2024_acs_local`	US local-area build. Build L, ~1.6M households, ACS multispine, PUMA-assigned to CD-119 / county / state	load by name, never implicit
`populace_uk_2023`	UK default (Microcosm, FRS+WAS)	private HF repo — set `HUGGING_FACE_TOKEN`

Verified manifest build ids (2026-07): US populace_us_2024 @ populace-us-2024-buildj-sparse-rmloss100-75d5add-20260710; UK populace_uk_2023 @ populace-uk-2023-dd68c73-.... The manifest also carries a dataset_overlays section (where the acs_local overlay lives) and per-region region_datasets.

The two defaults, precisely

There are two "default dataset" surfaces and they are not the same pin — know which one your code path hits:

from policyengine_us.system import DEFAULT_DATASET
assert "populace_us_2024" in DEFAULT_DATASET
assert "hf://datasets/policyengine/populace-us" in DEFAULT_DATASET

The pe.py managed default (what pe.us.calculate_household, managed_microsimulation, and ensure_datasets resolve): populace_us_2024 at the bundle-manifest build — populace-us-2024-buildj-sparse-...-20260710 (Build J, 2026-07-10).
The country-package DEFAULT_DATASET (what a bare from policyengine_us import Microsimulation; Microsimulation() uses, verified 1.764.6 at policyengine_us/system.py): the same dataset family populace_us_2024 on hf://datasets/policyengine/populace-us, but pinned to an earlier build (populace-us-2024-c86a631-...-20260619, 2026-06-19).

Both are Microcosm populace_us_2024 — even the country package's own test/dev default is now Microcosm (its test_microsim.py asserts "populace" in DEFAULT_DATASET). The takeaway: the country-package default can lag the certified bundle by a build. For reproducible, provenance- known results, go through the managed pe.* surface (which pins the certified bundle) rather than a bare country-package Microsimulation().

Local-area analysis: one national dataset, filtered

The local-area philosophy is one national dataset filtered by geography columns, never a file per area. populace_us_2024_acs_local is a single ~1.6M-household frame carrying state_fips, congressional_district_geoid, county, etc.; you scope it with a row filter, not by downloading a per-state or per-district file. The old per-area H5 artifacts no longer exist. See the policyengine skill for the RowFilterStrategy / region_registry / compute_*_impacts mechanics. This is why "give me the New York dataset" is the wrong mental model: there is one dataset, and New York is a filter on it.

Calibration diagnostics

Per-target calibration fit for the current release is browsable — no auth, reads the live release from Hugging Face — at calibration-diagnostics.vercel.app (JSON API under /calibration/dashboard/api/populace). Use it to see which admin targets a release hits and which it misses before trusting a number that depends on them. The policyengine-calibration- diagnostics skill covers the sensitivity registry and the three-ring reading method that turns those diagnostics into hypotheses about a score.

Where data work goes

New data work → the microcosm repo. Build plans, calibration targets, conditional models, release gates, the published registry.

policyengine-us-data is ARCHIVED (2026-07-02). The US enhancement path it owned (CPS + IRS-PUF imputation, calibration, its enhanced-CPS H5 releases, and the per-state / per-district H5s) is superseded by Microcosm and its per-area files were removed. Treat that repo as read-only history; do not target it with PRs.
policyengine-uk-data is still live as the UK input pipeline: it produces the enhanced FRS (Family Resources Survey, ~20k households) with wealth and other variables imputed from the Wealth and Assets Survey (WAS, ~20k households), which feeds the UK Microcosm build. UK imputations (e.g. wealth, student-loan balances) land here.

Institutional knowledge (archived-repo concepts, current mechanics)

The previous stack's packages are superseded, but the algorithms they implemented are exactly what Microcosm's fit and calibrate operators do. These concepts remain load-bearing:

Conditional-distribution imputation (QRF). Fill a variable missing from a recipient survey by learning it from a donor that has it, conditioning on shared predictors. PolicyEngine uses quantile regression forests, which predict the full conditional distribution (not a point estimate), so imputation preserves marginal shape, conditional relationships, and uncertainty — you sample from P(y | x) rather than pasting a mean. Quality is scored with quantile loss (lower is better; a distributional metric, unlike MSE). Classic US application: impute detailed tax-return components (capital-gains split, dividends) from the IRS PUF onto the CPS. Classic UK application: impute wealth from WAS onto FRS. In Microcosm this is microcosm-fit (weighted-bootstrap QRF, regime-gated), and the fit reads the frame's weights by construction.

Calibration = reweighting to hit targets. Given estimate contributions per record and known population totals, solve for weights so weighted sums match. The core relation:

achieved = estimate_matrix.T @ weights     # want: achieved ≈ targets
relative_error = abs(achieved - targets) / targets   # the diagnostic reported per target

Calibration owns representation (imputation/generation owns support). In Microcosm this is microcosm-calibrate, which is uncertainty-weighted evidence combination against targets with standard errors, not exact-hit — and the

# PolicyEngine data

How the microdata behind PolicyEngine population runs is built, calibrated, versioned, and
named. For *using* datasets in a simulation, see the `policyengine` skill (this skill is about
where the data comes from). For diagnosing why one score disagrees with a benchmark, see
`policyengine-calibration-diagnostics`.

The current data stack is **Microcosm** (repo `PolicyEngine/microcosm`, local mirror
`~/PolicyEngine/microcosm`; read its `README.md` + `DESIGN.md`). It replaced the technique-named
packages of the previous stack (microdf / microimpute / microcalibrate / L0 /
policyengine-us-data), which shared no datatype and had their worst bugs at the seams between
flat DataFrames.

## The Microcosm architecture

Microcosm is one kernel datatype — the **`Frame`** — with packages as operators on it. It is a
PEP 420 namespace (`microcosm.*`) shipped as independently-installable shard distributions, so an
analyst doing imputation never has to install torch and vice versa. Microcosm releases pin the
shards as a constellation.

| Package | Import | Role | Succeeds |
|---|---|---|---|
| `microcosm-frame` | `microcosm.frame` | the kernel: `Frame`, typed weights, strata, links, weighted accounting, unit structure, the RulesEngine protocol | microdf, microunit |
| `microcosm-fit` | `microcosm.fit` | conditional models (weight-aware by construction) | ad-hoc imputation scripts |
| `microcosm-calibrate` | `microcosm.calibrate` | targets → calibrated weights (APG / L0) | microcalibrate |
| `microcosm-build` | `microcosm.build` | build plans, donor graphs, release gates, country build stages | one-off build drivers |
| `microcosm-data` | `microcosm.data` | published population registry + lazy engine loaders | country-specific data packages |

Key design facts (from `DESIGN.md`) that change how you reason about the data:

- **The `Frame` is a weighted sampling frame of entity tables.** Person + group-entity tables
  with explicit `person_<group>_id` linkage established once at assembly — no operator
  re-derives person↔unit attachment from a flat frame. It carries **typed weights**
  (`design | importance | calibrated`, one vector per weighted entity) with conservation
  invariants the kernel enforces (strata mass sums; no silent zeroing; no NaN/negative), and
  **strata** giving every record explicit provenance (`cps_passthrough`,
  `synthetic_conditional`, `tail_verbatim`, ...). Generation owns support (oversample where it
  is scarce); calibration owns representation.
- **The rules engine is an adapter, not a dependency.** `microcosm.frame.rules.RulesEngine` is a
  Protocol (`variable_entity`, `variable_dtype`, `entity_schema`, `materialize`,
  `export_contract`, `write_dataset`). Today's adapter is `policyengine_us`; the Axiom
  `rulespec-us` adapter is written against the same protocol so the swap is a new adapter, not a
  migration.
- **`microcosm-fit` is weight-aware by construction** — fits read the frame's typed weights;
  there is no unweighted default. Canonical model: regime-gated, chained quantile forests with
  weights materialized by weighted bootstrap.
- **`microcosm-calibrate` is the only place calibrated weights are produced.** Sparse
  target-matrix compilation + APG / L0 pruning is the core, not an option — "generate big then
  prune" is the intended design (300k → 3M → 30M candidate pools pruned to a compact frame). Its
  longitudinal rule: **one weight per trajectory** (multi-period targets stack as
  `(target, period)` constraint rows over one weight vector).
- **Process rules are as binding as the architecture:** behavioral contract tests in CI from day
  one (weighted fits shift draws toward the weighted truth; calibration conserves declared mass;
  unit assignment partitions exactly); constellation versioning (consumers pin the constellation,
  not git SHAs); artifacts embed a certificate of the rules-engine + package versions that
  produced them; stage manifests are versioned artifacts with invariant checks.

The long-run goal in `DESIGN.md` ("The commons") is a communal, continuously-improving synthetic
population where the three contribution types *are* the package decomposition — **records**
(new strata at honest weights, `frame`), **conditional structure** (fitted `P(y|x)` models,
`fit` — the only way private sources contribute), and **facts** (targets with standard errors,
`calibrate` — Chronicle's lane). A contribution merges iff it improves the population's score on
held-out, rotated evidence without degrading a protected target family beyond tolerance.

## Certified releases → policyengine bundles

Builds that pass the release gates are published to Hugging Face (`policyengine/populace-us`,
`policyengine/populace-uk-private`) and referenced by name in the certified bundle manifest that
ships inside the `policyengine` package. Verified in policyengine 4.21.0 (`policyengine/data/
bundle/manifest.json`):

| Dataset | What | How to load |
|---|---|---|
| `populace_us_2024` | US default. Build J, sparse, ~57k households calibrated to tens of thousands of admin targets | resolves automatically; do not pass a raw URI |
| `populace_us_2024_acs_local` | US local-area build. Build L, ~1.6M households, ACS multispine, PUMA-assigned to CD-119 / county / state | load **by name**, never implicit |
| `populace_uk_2023` | UK default (Microcosm, FRS+WAS) | private HF repo — set `HUGGING_FACE_TOKEN` |

Verified manifest build ids (2026-07): US `populace_us_2024` @
`populace-us-2024-buildj-sparse-rmloss100-75d5add-20260710`; UK `populace_uk_2023` @
`populace-uk-2023-dd68c73-...`. The manifest also carries a `dataset_overlays` section (where the
`acs_local` overlay lives) and per-region `region_datasets`.

### The two defaults, precisely

There are two "default dataset" surfaces and they are *not* the same pin — know which one your
code path hits:

<!-- verify -->
```python
from policyengine_us.system import DEFAULT_DATASET
assert "populace_us_2024" in DEFAULT_DATASET
assert "hf://datasets/policyengine/populace-us" in DEFAULT_DATASET
```

- **The pe.py managed default** (what `pe.us.calculate_household`, `managed_microsimulation`, and
  `ensure_datasets` resolve): `populace_us_2024` at the **bundle-manifest** build —
  `populace-us-2024-buildj-sparse-...-20260710` (Build J, 2026-07-10).
- **The country-package `DEFAULT_DATASET`** (what a bare <!-- stale-ok -->
  `from policyengine_us import Microsimulation; Microsimulation()` uses, verified 1.764.6 at
  `policyengine_us/system.py`): the *same dataset family* `populace_us_2024` on
  `hf://datasets/policyengine/populace-us`, but pinned to an **earlier build**
  (`populace-us-2024-c86a631-...-20260619`, 2026-06-19).

Both are Microcosm `populace_us_2024` — even the country package's own test/dev default is now
Microcosm (its `test_microsim.py` asserts `"populace" in DEFAULT_DATASET`). The takeaway: the
country-package default can lag the certified bundle by a build. For reproducible, provenance-
known results, go through the managed `pe.*` surface (which pins the certified bundle) rather
than a bare country-package `Microsimulation()`.

## Local-area analysis: one national dataset, filtered

The local-area philosophy is **one national dataset filtered by geography columns, never a file
per area.** `populace_us_2024_acs_local` is a single ~1.6M-household frame carrying `state_fips`,
`congressional_district_geoid`, county, etc.; you scope it with a row filter, not by downloading
a per-state or per-district file. The old per-area H5 artifacts no longer exist. See the
`policyengine` skill for the `RowFilterStrategy` / `region_registry` / `compute_*_impacts`
mechanics. This is why "give me the New York dataset" is the wrong mental model: there is one
dataset, and New York is a filter on it.

## Calibration diagnostics

Per-target calibration fit for the current release is browsable — no auth, reads the live release
from Hugging Face — at **`calibration-diagnostics.vercel.app`** (JSON API under
`/calibration/dashboard/api/populace`). Use it to see which admin targets a release hits and
which it misses before trusting a number that depends on them. The `policyengine-calibration-
diagnostics` skill covers the sensitivity registry and the three-ring reading method that turns
those diagnostics into hypotheses about a score.

## Where data work goes

- **New data work → the `microcosm` repo.** Build plans, calibration targets, conditional models,
  release gates, the published registry.
<!-- stale-ok -->
- **`policyengine-us-data` is ARCHIVED (2026-07-02).** The US enhancement path it owned (CPS +
  IRS-PUF imputation, calibration, its enhanced-CPS H5 releases, and the per-state / per-district
  H5s) is superseded by Microcosm and its per-area files were removed. Treat that repo as
  read-only history; do not target it with PRs.
