Current 2014 population estimates published by the Department of Finance are available at the link below, for all municipalities in the State of California including San Diego, Imperial, Riverside, and Orange County. Current California Population Data By City: CAPopulation.xls This report provides revised population estimates as of January 1, 2013 and provisional population estimates as of January 1, 2014 for the state, counties, and cities and includes a calculation of annual percent change. These population estimates incorporate 2010 census counts. The methodology for the City and Unincorporated Area Estimates is based on housing units. The HUM is used to estimate total and occupied housing units, household size, household population, and group quarters population. Housing units are estimated by adding new construction and annexations and subtracting demolitions, and adjusting for units lost or gained by conversions. Annual housing unit change data are supplied by local jurisdictions and the U.S. Census Bureau. Occupied housing units are estimated by applying a derived civilian vacancy rate, based on 2010 benchmark data, to the estimated civilian housing units. Adjustments to census vacancy rates are made periodically. Exact data on foreclosures or other housing market indicators are not available to adjust vacancy rates. Military occupied housing units are added to civilian occupied housing units to calculate total occupied housing units. Military surveys are used to track military changes including base realignments and closures. Household population estimates are derived by multiplying the number of occupied housing units by the current persons per household. The persons per household estimates are based on 2010 census benchmark data and are adjusted by raking the current county population series into these estimates. The group quarters population is based on the Census Bureau’s 2010 SF1 File counts on group quarters and annually adjusted using reported changes for group quarters by state, federal, and local agencies. The household and group quarters populations are summed to produce the initial city population estimates. These estimates are aligned to the county estimates described below.
