According to the U.S. Census Bureau's Annual Population Estimates analysis the City of Wichita Falls was estimated to have a population of 104,724 residents as of July 1, 2016. The Census Bureau releases city and county population estimates annually. The official U.S. Census Bureau decennial census population count taken in 2010 was 104,553.
The Texas Demographic Center (University of Texas at San Antonio) also prepares annual population estimates for cities and counties within the state. According to their methodologies, the City of Wichita Falls had an estimated population of 105,033 as of January 1, 2016.Comparison of U.S. Census Bureau and Texas Demographic Center Population Estimates:
The estimates presented by the Texas Demographic Center differ from those from other sources, such as those periodically produced by the U.S. Census Bureau, for several reasons. The Texas Demographic Center estimates have been made using techniques that are different than those used by the Bureau. The Census Bureau uses only the distributive housing unit method to estimate place populations and the administrative records method to estimate county populations. Because the administrative records method uses income tax data that are not available to analysts outside the Census Bureau, this technique cannot be used by other agencies. In addition, the estimates from the Texas Demographic Center utilize more recent data than those used by the U.S. Bureau of the Census. The Census Bureau's county estimates utilize 2014 birth and death data, whereas 2015 values were employed in the Texas Demographic Center estimates. Also, the Census Bureau utilizes birth and death data only in their county level estimates while the Texas Demographic Center includes current births and deaths in both county and place level estimates. Finally, the Census Bureau estimates include legal boundary updates reported before January 1, 2015 but do not include more recent information for places, whereas information on annexation and boundary changes through the 2015 calendar year were included in the estimates completed by the Texas program. Because of these differences, the population estimates from the Texas Demographic Center and those from the U.S. Bureau of the Census are not directly comparable.
