How to read the evidence

Methodology

Texas governing definitions, direct ZIP/ZCTA evidence, legislative geography, and supplemental workforce context are kept separate.

How to Read the Rankings

Ranks are ranks by numeric value, not best-to-worst judgments. A high value can mean different things in different columns.

Childcare Desert Formula

The Texas/TWC-compatible measure divides children under age six with working parents by current qualifying regulated childcare capacity. A ratio of at least 3.0 is a desert; positive demand with zero qualifying capacity is also a desert.

Who the Formula Does Not Count

This companion measure is total children under six minus children under six with working parents. It is not a claim that every child outside the denominator requires licensed childcare.

HHSC Nighttime-Care Standard

The governing Texas nighttime-care window is 9:00 p.m.-6:00 a.m. Capacity at a schedule-overlap operation is not the same as nighttime seat availability.

ACS B08302 Early-Shift Workforce

ACS B08302 describes when workers leave home to go to work. The before-6-a.m. measure is supplemental workforce-time context and does not identify childcare use.

LODES Workforce Geography

LODES describes worker residence and workplace geography. It does not identify childcare stops, actual travel routes, or commute duration.

ZIP-to-Legislative-District Crosswalk

The site uses the governed 2025 ZIP-to-SLDL and ZIP-to-SLDU crosswalks used by the Texas legislative intelligence architecture. Texas is explicitly scoped before aggregation and split ZIPs are preserved.

Duplicate ZIP×district relationships are governed with MAX(area_ratio), never SUM(area_ratio).

District Area-Ratio Allocation

For additive quantities such as children, qualifying capacity, operations, and worker counts, the ZIP value is multiplied by area_ratio — the share of that ZIP's geographic area inside the district — and the allocated values are summed. District ratios are then recomputed from those allocated components.

What the District Numbers Mean

ZIP/ZCTA desert classification = direct Texas-compatible evidence.
House/Senate district ratio = legislative context estimate.

The district method is geographic allocation, not Census-block assignment, child-level assignment, household-level assignment, population-weighted allocation, or a statistical confidence interval.

Downloadable Evidence

Each district page provides its ZIP contribution crosswalk, and the Downloads area retains the ZIP, House, Senate, methodology, CSV, Markdown and text evidence products.

House Crosswalk Duplicate Governance

The 2025 Texas House ZIP crosswalk source contained duplicate ZIP×district rows. Before any House district allocation, the publication now reduces each ZIP×district relationship to a single governed record using MAX(area_ratio), never SUM(area_ratio). The correction prevents duplicated additive district estimates while preserving split ZIP relationships.

Plain-Language Terms Used on This Site

Who the Formula Does Not Count: children under age six outside the working-parent denominator used in the Texas-compatible childcare desert calculation. This is a denominator-transparency measure, not an estimate that every child outside the denominator needs licensed childcare.
Operation overlapping the HHSC nighttime window: a childcare operation whose source-reported schedule overlaps any portion of HHSC’s 9 p.m.–6 a.m. nighttime-care window. This does not mean the operation is open for the entire window or that all authorized capacity is available at night.
