Data and Methodology
Populations are estimated using local development permits completed in the City and County since the most recent Census on April 1, 2020. New and demolished dwelling units, after July 1, 2020, are totaled then multiplied by average Persons Per Household (PPH) and by a current Occupancy Rate (OR). Both the PPH and the OR are determined from the American Community Survey (ACS) when the population estimate was calculated.
Data Formula Total New Dwelling Units for each Administrative Boundary (after July 1, 2020) x Current PPH x Current OR = Current Estimated Population
All Permit Data (GIS Shapefile) - See attribute table column labeled DWELLING_UNITS. When calculating demolitions, all values must be converted to a negative value.
Census ACS - Vacancy Rate - The occupancy rate is an inverse of the current regional vacancy rate reported by the US Census. For example, if the vacancy rate is 5%, then the current occupancy rate will be 95% or 0.95.
