• compare_zipsCompare ZIPs

  Rank several ZIPs by a single metric, highest value first. `zips`: a list of 5-digit US ZIPs to compare. `metric`: one of `population`, `median_age`, `median_household_income`, `per_capita_income`, `households_200k_plus_pct`, `median_home_value`, `median_gross_rent`, `owner_occupied_pct`, `bachelors_plus_pct`, `graduate_or_professional_pct`. Returns each ZIP's value, sorted descending; ZIPs with no data (suppressed or no ZCTA) are listed last. All values are ACS 5-year estimates.

• find_zipsFind ZIPs for a place

  Reverse lookup: the ZIPs (ZCTAs) that fall within a named place. `place`: a U.S. place name — an incorporated city/town or a census-designated place (e.g. 'Cambridge', 'West Hollywood'); the Census descriptor is optional ('Cambridge' and 'Cambridge city' both work). `state`: optional 2-letter USPS code or full state name to disambiguate (many places share a name). Returns the ZCTAs intersecting that place, ranked by `coverage_pct` — the share of each ZCTA's land that lies within the place. This is approximate: ZCTAs don't nest inside places, so a ZIP may span several places and vice versa. Bu…

• get_acs_variableGet a raw ACS variable

  Raw value of a single ACS variable for a ZIP — an escape hatch. `zip_code`: a 5-digit US ZIP. `variable`: an ACS variable code (e.g. `B19013_001E`) or the friendly store-column name (e.g. `median_household_income`); both match case-insensitively. Returns that one value for the ZIP. Limited to the variables held in the local store (the same ones the other tools draw on); an unknown variable errors with the full list.

• get_demographicsGet demographics by ZIP

  Population and median age for a ZIP. `zip_code`: a 5-digit US ZIP. Returns the total population and the median age of residents — both ACS 5-year estimates. (Age-bracket breakdowns, e.g. under-18 / 18-34 / 35-64 / 65+, are on the roadmap.)

• get_educationGet education by ZIP

  Educational attainment for a ZIP: % bachelor's+ and % graduate degree. `zip_code`: a 5-digit US ZIP. Of the population aged 25 and over, returns the percent with a bachelor's degree or higher and the percent with a graduate or professional degree — ACS 5-year estimates.

• get_housingGet housing by ZIP

  Housing measures for a ZIP: home value, rent, and owner-occupied share. `zip_code`: a 5-digit US ZIP. Returns the median value of owner-occupied homes, the median gross rent (monthly), the number of occupied housing units, and the percent that are owner-occupied — all ACS 5-year estimates. Note: ACS top-codes median home value at $2,000,001, so the priciest ZIPs (e.g. Atherton 94027) report exactly that — read it as "$2M or more," not an exact value.

• get_incomeGet income by ZIP

  Income measures for a ZIP: median household, per-capita, and % $200k+. `zip_code`: a 5-digit US ZIP. Returns median household income, per-capita income, the number of households, and the percent of households earning $200k+ — all ACS 5-year estimates in USD. Note: ACS top-codes median household income at $250,001, so the wealthiest ZIPs (e.g. Atherton 94027) report exactly that — read it as "$250k or more," not an exact figure.

• lookup_zipLook up a ZIP

  Confirm a ZIP maps to a Census ZCTA and return its name and population. `zip_code`: a 5-digit US ZIP. A good first call to validate a ZIP before asking for more detail. Returns the ZCTA, Census area name, total population, and the ACS data vintage. ZIP ≈ ZCTA; ~2% of ZIPs have no ZCTA and error.
