Final answer:
Texas is likely to gain additional seats in the U.S. House of Representatives after the 2020 census and reapportionment if the state's population has increased from its 2010 total.
Step-by-step explanation:
Given that the Texas population is expected to increase from its 2010 total, after the 2020 census and subsequent reapportionment, Texas will most likely gain additional seats in the U.S. House of Representatives. This is due to the congressional apportionment process which allocates seats based on population data collected every ten years by the U.S. Census Bureau. While the total number of House seats is capped at 435, population shifts among the states can lead to some states gaining representatives at the expense of others who lose them. In Texas's case, an increase in population typically results in a gain of representation in Congress to reflect the state's growing population demands and to ensure equal representation.
Congressional apportionment today employs the equal proportions method involving a mathematical formula, and redistricting ensures that legislative districts are redrawn to maintain a similar number of voters in each, while still conforming to the total number of 435 districts.
