Demographic data is critical in planning the future transportation system. Demographic data is composed of employment, housing units, and population. Each of these components serves different aspects in the transportation planning process. Employment and housing units are used in travel demand modeling. Population projections have lots of uses, including economic projection, demand management, and comparisons between communities.
The demographic projection process started in October 2021. The 2020 U.S. Census results provided the population and housing information. The 2020 employment control total was provided by the Bureau of Economic Analysis. The Census data showed that the BTPO area did not grow at the rate predicted in the 2015 demographic update. Woods and Poole Economics provided the population and housing projections for 2050. Their 2020 projections were similar to the Census data. The Bureau of Economic Analysis data was used for 2050 employment projections.
A complete explanation of the methodology used is included in the Population Housing and Employment Forecasts report.
