El Paso County is in the midst of its slowest population growth rate in 80 years, driven largely by a flight of residents to other U.S. communities from the Texas border county, new estimates from the U.S. Census Bureau show. The county’s population in 2018 was an estimated 840,758, up from just over 800,000 at the time of the 2010 census. That means El Paso County has had an average annual population growth rate of 0.5% since the last census, compared to 0.6% nationally and 1.5% in Texas. The 0.5% annual population growth since the 2010 census is the slowest rate of growth since the period between 1930 and 1940, during the Great Depression, when El Paso County lost population at a rate of about 0.6% a year. El Paso’s annual growth rate between 2000 and 2010 was 1.4%, almost three times the current growth rate.
