State and local housing credit agencies that allocate low-income housing tax credits and states and other issuers of tax-exempt private activity bonds have been provided with a listing of the proper population figures to be used when calculating the 2025:

• calendar-year population-based component of the state housing credit ceiling under Code Sec. 42(h)(3)(C)(ii);
• calendar-year private activity bond volume cap under Code Sec. 146; and
• exempt facility bond volume limit under Code Sec. 142(k)(5)

These figures are derived from the estimates of the resident populations of the 50 states, the District of Columbia and Puerto Rico, which were released by the Bureau of the Census on December 19, 2024. The figures for the insular areas of American Samoa, Guam, the Northern Mariana Islands and the U.S. Virgin Islands are the midyear population figures in the U.S. Census Bureau's International Database.
