What is a Census Tract?
- Census tracts are small, relatively permanent statistical subdivisions of a county. The U.S. Census Bureau uses the census tract geographic boundary system to collect, tabulate, and present decennial census and other data. Census tracts generally have between 1,500 and 8,000 residents. There are a total of 715 census tracts in the region.

What is a Census Designated Place (CDP)?
- CDPs are unincorporated communities that are identifiable by name, with concentrations of population, housing and commercial structures. They are delineated for each decennial census for reporting purposes, and are the statistical counterparts of incorporated municipalities. CDP boundaries may change from one decennial census to the next.

What is a Forecast Analysis Zone (FAZ)?
- FAZs are the units of the geographic boundary system used by the PSRC to model and report its small area Forecasts of Population, Households, and Employment. They are built up from traffic analysis zones (TAZs), with each FAZ containing between 1 to 20 TAZs. FAZ boundaries generally, with few exceptions, also line up with census tract boundaries, with each FAZ containing between 1 to 9 census tracts. There are a total of 219 FAZs in the region.

What is a Traffic Analysis Zone (TAZ)?
- TAZs are the units of the geographic boundary system used by the PSRC to run and report results from its Travel Demand Forecast Model. The TAZs nest within a larger Forecast Analysis Zone (FAZ) geographic boundary system, with each FAZ containing between 1 and 20 TAZs. TAZ boundaries generally, with few exceptions, also line up with census tract boundaries, with each census tract containing between 1 to 9 TAZs. There are a total of 938 TAZs in the region.
