1–Preliminary; 2–Revised
Note: The U.S. Census department changed its construction categories beginning with its May 2003 statistics.
With the changes in the project classifications, data now presented are not directly comparable with those data previously published in the regular-format press releases and tables. Direct comparisons can only be made at the total, total private, total state and local, total federal, and total public levels for annual and not seasonally adjusted monthly data.
