What ProMap is

ProMap is an interactive map of the United States with 139 measures of housing, people and places: home prices and rents, listings and sales, affordability, schools, crime, income and demographics, property taxes, insurance, climate and hazard risk, jobs, migration, building permits and election results. It is made by Aziz Sunderji at Home Economics, an independent housing research and data studio.

Pick a measure, search for any place, and the map shades every area. Click an area for its figure, its rank and how it compares with its metro area, its state and the U.S. Many measures have a history chart, a ranking, a table and a share card.

Areas: states, metro areas, counties, cities and ZIP codes; many measures go down to census tracts and block groups, and several are drawn as hexagons or as dots (one dot per group of people or jobs, one point per school, data center, fatal crash or permit office). The finest area for each measure is in the table below.

Places with Zillow home-value or rent figures (September 2026): 51 states including the District of Columbia, 925 metro areas, 3,071 counties, 19,448 cities and 26,285 ZIP codes. Each has its own free page, for example Tennessee, the Nashville metro area and ZIP code 37215.

Measures: 139, in 22 groups. 3 are free on the map (home prices, rents, data centers); the others are in ProMap Plus.

The map is free to open and explore. ProMap Plus costs $19 a month or $190 a year and unlocks the other measures, the longer time horizons, dollar levels, property-type cuts, and tools such as saved views and the CSV download. A free 7-day trial of ProMap Plus is offered on the map.

ProMap is built and maintained by Aziz Sunderji, the founder of Home Economics. Before Home Economics he spent fifteen years in financial markets, directing research at Barclays Investment Bank, and then worked at the Wall Street Journal on data-driven explanatory reporting. Home Economics publishes chart-driven analysis of the U.S. housing market and builds data tools.
