PolicyEngine Python analysis

The policyengine package (repo: PolicyEngine/policyengine.py) is the canonical Python interface for both single-household calculations and population microsimulation. It pins a certified model + data bundle, so results are reproducible and the data provenance is known.

Originally verified against policyengine 4.21.0 (2026-07); the marked examples re-run in CI against the latest release (5.0.1 at 2026-08). Re-verify the bundle when precision matters (see "Checking what you're running" below).

Setup

Country models are extras — bare policyengine installs neither:

uv pip install "policyengine[us]"   # US model + certified US data bundle
uv pip install "policyengine[uk]"   # UK model (population data needs HUGGING_FACE_TOKEN)
uv pip install "policyengine"       # both countries

Analysis always runs on the latest released policyengine (>=5.0.1; resolve "latest" from PyPI as described in "Checking what you're running"). Each release pins exactly-matched country-model versions and the certified data bundle, which is what makes results reproducible. Directly-imported country packages (policyengine_us / policyengine_uk) are for model development and tests, not for analysis compute.

Household calculations (fast, ~2 GB RAM)

calculate_household answers "what does this specific household get/pay?" — no dataset download, runs in seconds.

import policyengine as pe

result = pe.us.calculate_household(
    people=[{"age": 40, "employment_income": 50_000}, {"age": 8}],
    tax_unit={"filing_status": "HEAD_OF_HOUSEHOLD"},
    household={"state_code": "CA"},
    year=2026,
    extra_variables=["income_tax"],
)
assert result.tax_unit.ctc == 2_200          # OBBBA CTC, 2026
assert round(result.household.household_net_income) == 46_358
print(result.spm_unit.snap, result.tax_unit.eitc, result.tax_unit.income_tax)

Result access is dot-attribute on singular entities — result.tax_unit.ctc, never result.tax_unit[0]["ctc"]. Only result.person is a list (result.person[0].age). Entities: person[i], marital_unit, family, spm_unit, tax_unit, household (US); person[i], benunit, household (UK).

Each entity exposes a limited default column set — accessing anything else raises AttributeError listing what's available and telling you the fix: pass extra_variables=["variable_name"] to materialize it (as with income_tax above; the default person columns don't include it).

Reforms are a flat dict of {parameter_path: value}:

import policyengine as pe

baseline = pe.us.calculate_household(
    people=[{"age": 40, "employment_income": 50_000}, {"age": 8}],
    tax_unit={"filing_status": "HEAD_OF_HOUSEHOLD"},
    household={"state_code": "CA"},
    year=2026,
)
reformed = pe.us.calculate_household(
    people=[{"age": 40, "employment_income": 50_000}, {"age": 8}],
    tax_unit={"filing_status": "HEAD_OF_HOUSEHOLD"},
    household={"state_code": "CA"},
    year=2026,
    reform={"gov.irs.credits.ctc.amount.base[0].amount": 3_000},
)
assert reformed.tax_unit.ctc == 3_000
assert reformed.household.household_net_income - baseline.household.household_net_income == 800

UK works the same way:

uk = pe.uk.calculate_household(
    people=[{"age": 35, "employment_income": 50_000}],
    year=2026,
)
uk.person[0].income_tax
uk.household.hbai_household_net_income

To sweep an input (e.g. earnings 0→200k for an MTR curve), pass axes. Every variable on the result then comes back as a list of values across the sweep instead of a scalar:

import policyengine as pe

result = pe.us.calculate_household(
    people=[{"age": 40}],
    tax_unit={"filing_status": "SINGLE"},
    household={"state_code": "TX"},
    year=2026,
    axes=[[{"name": "employment_income", "min": 0, "max": 200_000, "count": 401}]],
)
earnings = result.person[0].employment_income      # [0.0, 500.0, ..., 200000.0]
net = result.household.household_net_income        # list of 401 values
assert len(earnings) == len(net) == 401
assert earnings[1] == 500.0

Population analysis (heavy: tens of GB RAM, minutes per simulation)

The canonical population flow builds year-specific datasets from the certified bundle, then runs baseline and reform Simulations:

import policyengine as pe
from policyengine.core import Simulation

datasets = pe.us.ensure_datasets(years=[2026], data_folder="./data")
dataset = next(iter(datasets.values()))

baseline = Simulation(dataset=dataset, tax_benefit_model_version=pe.us.model)
reform = Simulation(
    dataset=dataset,
    tax_benefit_model_version=pe.us.model,
    policy={"gov.irs.credits.ctc.amount.base[0].amount": 3_000},
)

analysis = pe.us.economic_impact_analysis(baseline, reform)
budget = pe.us.calculate_budgetary_impact(baseline, reform)
print(f"Total budgetary impact: ${budget.total / 1e9:,.1f}B "
      f"(federal ${budget.federal / 1e9:,.1f}B, state ${budget.state / 1e9:,.1f}B)")
for d in analysis.decile_impacts.outputs:
    print(d.decile, d.absolute_change, d.relative_change)

Key facts:

  • Call economic_impact_analysis before (or instead of) manual ensure(). It configures conditionally-materialized output variables (e.g. federal_benefit_cost) and ensures both simulations. If you call Simulation.ensure() yourself and then calculate_budgetary_impact, it fails with "variable ... is not present in simulation output data" — the fix is pe.us.economic_impact_analysis(baseline, reform) first, or configure_budgetary_impact_variables on each simulation before ensure().
  • economic_impact_analysis returns a PolicyReformAnalysis: decile_impacts, program_statistics, baseline_poverty / reform_poverty (by measure and demographic group), baseline_inequality / reform_inequality (Gini, top shares). Each OutputCollection exposes .outputs (typed) and .dataframe.
  • calculate_budgetary_impact partitions into total / federal / state / unattributed. Sign convention: positive = government better off. total is Δhousehold_tax − Δhousehold_benefits plus shared-funding health-program cost (Medicaid/CHIP/MSP), so it captures cascading interactions — never score a reform by summing the directly-modified program variable alone.
  • Memory/time: a full US population simulation is tens of GB of RAM and several minutes; a baseline+reform pair with full outputs took ~15 minutes on a 128 GB machine. Run ONE heavy simulation pipeline at a time. Household calculations are the cheap path — prefer them whenever the question is about specific households.
  • Simulation(policy={...}) takes the same flat reform dict as calculate_household.
Aggregates and filters

For a single number (program spending, revenue, caseload), use Aggregate / ChangeAggregate instead of the full analysis bundle:

from policyengine.outputs import Aggregate, AggregateType

ca_snap = Aggregate(
    simulation=baseline,
    variable="snap",
    aggregate_type=AggregateType.SUM,
    filter_variable="state_code",
    filter_variable_eq="CA",
)
ca_snap.run()
ca_snap.result
The managed country-package surface (MicroSeries)

managed_microsimulation returns a country-package Microsimulation pinned to the certified bundle — the required route whenever you want the familiar .calc() / MicroSeries analyst surface (pe.uk.managed_microsimulation() is the UK twin; kwargs such as reform= forward to the country package's constructor):

import policyengine as pe

sim = pe.us.managed_microsimulation()               # certified default dataset
sim.policyengine_bundle                             # provenance: model + data release pins
income = sim.calc("household_net_income", period=2026, map_to="person")
income.mean()          # weighted mean
income.median()        # weighted median
income.gini()          # weighted Gini
(income < 30_000).mean()   # weighted share

MicroSeries (from microdf-python, still a live dependency of policyengine-us and core) embeds survey weights in every operation. Discipline:

  • Never strip weights: no np.array(series), .values, .to_numpy(), .astype(...) mid-analysis, and never fetch household_weight/person_weight yourself — map_to= handles entity projection and weighting.
  • Weighted stats are the methods themselves: .sum(), .mean(), .median(), .quantile(q), .gini(), .top_x_pct_share(x). (decile_values() / percentile() do not exist.)
  • Don't subtract boolean MicroSeries (numpy ≥2.4 raises TypeError): compute .mean() rates first, then subtract floats.
  • US Microsimulation uses .calc(...); UK uses .calculate(...).
  • Arbitrary dataset URIs require allow_unmanaged=True — if you reach for that, you are leaving the certified bundle and should say so in your results.

Direct from policyengine_us import Microsimulation (unmanaged, whatever data it defaults to) is deprecated for analysis — its default dataset can lag the certified bundle, so results are not provenance-known. It remains fine for country-model development and tests inside the model repos. Any population number you report must come through the managed surface above.

Datasets

Certified defaults resolve automatically — do not pass raw hf:// URIs:

NameWhatNotes
populace_us_2024US default (Microcosm, ~57k households calibrated to ~30k+ admin targets)public
populace_us_2024_acs_localUS local-area build (~1.6M households, ACS multispine, PUMA-assigned CD-119/county/state)load by name for state/district work; never selected implicitly
populace_uk_2023UK default (Microcosm)private HF repo — set HUGGING_FACE_TOKEN

The pre-2026 datasets are gone:

enhanced_cps_2024 and enhanced_frs_2023_24 are superseded by Microcosm, and the per-area

files (hf://policyengine/policyengine-us-data/states/*.h5, districts/*.h5) no longer exist — policyengine-us-data is archived. Local-area analysis = filter one national dataset by its geography columns, never a per-area file. See the policyengine-data skill for how Microcosm is built and calibrated.

# PolicyEngine Python analysis

The `policyengine` package (repo: PolicyEngine/policyengine.py) is the canonical Python
interface for both single-household calculations and population microsimulation. It pins a
certified model + data bundle, so results are reproducible and the data provenance is known.

Originally verified against policyengine 4.21.0 (2026-07); the marked examples re-run in CI
against the latest release (5.0.1 at 2026-08). Re-verify the bundle when precision matters
(see "Checking what you're running" below).

## Setup

Country models are extras — bare `policyengine` installs neither:

```bash
uv pip install "policyengine[us]"   # US model + certified US data bundle
uv pip install "policyengine[uk]"   # UK model (population data needs HUGGING_FACE_TOKEN)
uv pip install "policyengine"       # both countries
```

Analysis always runs on the **latest released** `policyengine` (`>=5.0.1`; resolve "latest"
from PyPI as described in "Checking what you're running"). Each release pins exactly-matched
country-model versions and the certified data bundle, which is what makes results
reproducible. Directly-imported country packages (`policyengine_us` / `policyengine_uk`) are
for model development and tests, not for analysis compute.

## Household calculations (fast, ~2 GB RAM)

`calculate_household` answers "what does this specific household get/pay?" — no dataset
download, runs in seconds.

<!-- verify -->
```python
import policyengine as pe

result = pe.us.calculate_household(
    people=[{"age": 40, "employment_income": 50_000}, {"age": 8}],
    tax_unit={"filing_status": "HEAD_OF_HOUSEHOLD"},
    household={"state_code": "CA"},
    year=2026,
    extra_variables=["income_tax"],
)
assert result.tax_unit.ctc == 2_200          # OBBBA CTC, 2026
assert round(result.household.household_net_income) == 46_358
print(result.spm_unit.snap, result.tax_unit.eitc, result.tax_unit.income_tax)
```

Result access is **dot-attribute on singular entities** — `result.tax_unit.ctc`, never
`result.tax_unit[0]["ctc"]`. Only `result.person` is a list (`result.person[0].age`). Entities:
`person[i]`, `marital_unit`, `family`, `spm_unit`, `tax_unit`, `household` (US);
`person[i]`, `benunit`, `household` (UK).

**Each entity exposes a limited default column set** — accessing anything else raises
`AttributeError` listing what's available and telling you the fix: pass
`extra_variables=["variable_name"]` to materialize it (as with `income_tax` above; the
default person columns don't include it).

Reforms are a **flat dict** of `{parameter_path: value}`:

<!-- verify -->
```python
import policyengine as pe

baseline = pe.us.calculate_household(
    people=[{"age": 40, "employment_income": 50_000}, {"age": 8}],
    tax_unit={"filing_status": "HEAD_OF_HOUSEHOLD"},
    household={"state_code": "CA"},
    year=2026,
)
reformed = pe.us.calculate_household(
    people=[{"age": 40, "employment_income": 50_000}, {"age": 8}],
    tax_unit={"filing_status": "HEAD_OF_HOUSEHOLD"},
    household={"state_code": "CA"},
    year=2026,
    reform={"gov.irs.credits.ctc.amount.base[0].amount": 3_000},
)
assert reformed.tax_unit.ctc == 3_000
assert reformed.household.household_net_income - baseline.household.household_net_income == 800
```

UK works the same way:

```python
uk = pe.uk.calculate_household(
    people=[{"age": 35, "employment_income": 50_000}],
    year=2026,
)
uk.person[0].income_tax
uk.household.hbai_household_net_income
```

To sweep an input (e.g. earnings 0→200k for an MTR curve), pass `axes`. Every variable on the
result then comes back as a **list of values across the sweep** instead of a scalar:

<!-- verify -->
```python
import policyengine as pe

result = pe.us.calculate_household(
    people=[{"age": 40}],
    tax_unit={"filing_status": "SINGLE"},
    household={"state_code": "TX"},
    year=2026,
    axes=[[{"name": "employment_income", "min": 0, "max": 200_000, "count": 401}]],
)
earnings = result.person[0].employment_income      # [0.0, 500.0, ..., 200000.0]
net = result.household.household_net_income        # list of 401 values
assert len(earnings) == len(net) == 401
assert earnings[1] == 500.0
```

## Population analysis (heavy: tens of GB RAM, minutes per simulation)

The canonical population flow builds year-specific datasets from the certified bundle, then
runs baseline and reform `Simulation`s:

<!-- verify: slow -->
```python
import policyengine as pe
from policyengine.core import Simulation

datasets = pe.us.ensure_datasets(years=[2026], data_folder="./data")
dataset = next(iter(datasets.values()))

baseline = Simulation(dataset=dataset, tax_benefit_model_version=pe.us.model)
reform = Simulation(
    dataset=dataset,
    tax_benefit_model_version=pe.us.model,
    policy={"gov.irs.credits.ctc.amount.base[0].amount": 3_000},
)

analysis = pe.us.economic_impact_analysis(baseline, reform)
budget = pe.us.calculate_budgetary_impact(baseline, reform)
print(f"Total budgetary impact: ${budget.total / 1e9:,.1f}B "
      f"(federal ${budget.federal / 1e9:,.1f}B, state ${budget.state / 1e9:,.1f}B)")
for d in analysis.decile_impacts.outputs:
    print(d.decile, d.absolute_change, d.relative_change)
```

Key facts:

- **Call `economic_impact_analysis` before (or instead of) manual `ensure()`.** It configures
  conditionally-materialized output variables (e.g. `federal_benefit_cost`) and ensures both
  simulations. If you call `Simulation.ensure()` yourself and then
  `calculate_budgetary_impact`, it fails with "variable ... is not present in simulation
  output data" — the fix is `pe.us.economic_impact_analysis(baseline, reform)` first, or
  `configure_budgetary_impact_variables` on each simulation before `ensure()`.
- `economic_impact_analysis` returns a `PolicyReformAnalysis`: `decile_impacts`,
  `program_statistics`, `baseline_poverty` / `reform_poverty` (by measure and demographic
  group), `baseline_inequality` / `reform_inequality` (Gini, top shares). Each
  `OutputCollection` exposes `.outputs` (typed) and `.dataframe`.
- `calculate_budgetary_impact` partitions into `total` / `federal` / `state` /
  `unattributed`. Sign convention: **positive = government better off**. `total` is
  Δhousehold_tax − Δhousehold_benefits plus shared-funding health-program cost
  (Medicaid/CHIP/MSP), so it captures cascading interactions — never score a reform by
  summing the directly-modified program variable alone.
- **Memory/time**: a full US population simulation is tens of GB of RAM and several minutes;
  a baseline+reform pair with full outputs took ~15 minutes on a 128 GB machine. Run ONE
  heavy simulation pipeline at a time. Household calculations are the cheap path — prefer
  them whenever the question is about specific households.
- `Simulation(policy={...})` takes the same flat reform dict as `calculate_household`.

### Aggregates and filters

For a single number (program spending, revenue, caseload), use `Aggregate` /
`ChangeAggregate` instead of the full analysis bundle:

```python
from policyengine.outputs import Aggregate, AggregateType

ca_snap = Aggregate(
    simulation=baseline,
    variable="snap",
    aggregate_type=AggregateType.SUM,
    filter_variable="state_code",
    filter_variable_eq="CA",
)
ca_snap.run()
ca_snap.result
```

### The managed country-package surface (MicroSeries)

`managed_microsimulation` returns a country-package `Microsimulation` pinned to the certified
bundle — the required route whenever you want the familiar `.calc()` / MicroSeries analyst
surface (`pe.uk.managed_microsimulation()` is the UK twin; kwargs such as `reform=` forward
to the country package's constructor):

```python
import policyengine as pe

sim = pe.us.managed_microsimulation()               # certified default dataset
sim.policyengine_bundle                             # provenance: model + data release pins
income = sim.calc("household_net_income", period=2026, map_to="person")
income.mean()          # weighted mean
income.median()        # weighted median
income.gini()          # weighted Gini
(income < 30_000).mean()   # weighted share
```

MicroSeries (from `microdf-python`, still a live dependency of policyengine-us and core)
embeds survey weights in every operation. Discipline:

- **Never** strip weights: no `np.array(series)`, `.values`, `.to_numpy()`, `.astype(...)`
  mid-analysis, and never fetch `household_weight`/`person_weight` yourself — `map_to=`
  handles entity projection and weighting.
- Weighted stats are the methods themselves: `.sum()`, `.mean()`, `.median()`,
  `.quantile(q)`, `.gini()`, `.top_x_pct_share(x)`. (`decile_values()` / `percentile()` do
  not exist.)
- Don't subtract boolean MicroSeries (numpy ≥2.4 raises `TypeError`): compute
  `.mean()` rates first, then subtract floats.
- US `Microsimulation` uses `.calc(...)`; UK uses `.calculate(...)`.
- Arbitrary dataset URIs require `allow_unmanaged=True` — if you reach for that, you are
  leaving the certified bundle and should say so in your results.

<!-- stale-ok -->
Direct `from policyengine_us import Microsimulation` (unmanaged, whatever data it defaults
to) is **deprecated for analysis** — its default dataset can lag the certified bundle, so
results are not provenance-known. It remains fine for country-model development and tests
inside the model repos. Any population number you report must come through the managed
surface above.

## Datasets

Certified defaults resolve automatically — **do not pass raw `hf://` URIs**:

| Name | What | Notes |
|---|---|---|
| `populace_us_2024` | US default (Microcosm, ~57k households calibrated to ~30k+ admin targets) | public |
| `populace_us_2024_acs_local` | US local-area build (~1.6M households, ACS multispine, PUMA-assigned CD-119/county/state) | load **by name** for state/district work; never selected implicitly |
| `populace_uk_2023` | UK default (Microcosm) | private HF repo — set `HUGGING_FACE_TOKEN` |

The pre-2026 datasets are gone:
<!-- stale-ok -->
`enhanced_cps_2024` and `enhanced_frs_2023_24` are superseded by Microcosm, and the per-area
<!-- stale-ok -->
files (`hf://policyengine/policyengine-us-data/states/*.h5`, `districts/*.h5`) no longer
