Sub-County Forecast Series (Updated April 27, 2016)
Periodically, demographic forecasts for housing units, households, population, and employment are produced for Loudoun County's 282 Traffic Analysis Zones (TAZs) – providing a relatively fine-grained picture of development forecasts in five-year increments through 2045. Loudoun County submits its TAZ forecasts to the Metropolitan Washington Council of Governments (COG). COG finalizes the region’s forecasts approximately six months after all local jurisdictions have submitted their forecasts. Loudoun County also summarizes this data, using its larger planning subareas. There are 10 planning subareas, compared to 282 TAZs.
Round 9.0 is Loudoun County's most recently released set of forecasts. Loudoun County submitted it to COG on March 21, 2016. Round 9.0 reflects recent development activity, market conditions, rezonings, comprehensive plan amendments, and rail arriving in 2020. The forecasts also reflect approved projects remaining to be built, the county's planned land use, the county's long-range supply of land, and land use/development constraints.
