Title: Privately Owned Housing Starts Authorized by Building Permits: 1-Unit Structures for Washington-Arlington-Alexandria, DC-VA-MD-WV (MSA) Series ID: WASH911BP1FHSA Source: Federal Reserve Bank of St. Louis Release: Housing Units Authorized By Building Permits (Seasonally Adjusted) (Not a Press Release) Seasonal Adjustment: Seasonally Adjusted Frequency: Monthly Units: Units Date Range: 1988-01-01 to 2013-03-01 Last Updated: 2013-04-24 8:47 AM CDT Notes: The data services of the Federal Reserve Bank of St. Louis include series that are seasonally adjusted. To make these adjustments, we use the X-12 Procedure of SAS to remove the seasonal component of the series so that non-seasonal trends can be analyzed. This procedure is based on the U.S. Bureau of the Census X-12-ARIMA Seasonal Adjustment Program. More information on this program can be found at http://www.census.gov/srd/www/x12a/. The seasonal moving average function used is that of the Census Bureau's X-11-ARIMA program. This includes a 3x3 moving average for the initial seasonal factors and a 3x5 moving average to calculate the final seasonal factors. The D11 function is also used to output the entire seasonally adjusted series that is displayed.
