THE ASTONISHING RISE OF UNINCORPORATED HARRIS COUNTY You already knew that more people in Harris County live outside Beltway 8 than inside it, right? And that of the people residing inside the Beltway, fewer than a quarter live inside the Loop? Here’s another nugget contained in the latest Harris County population report: the population of Harris County’s unincorporated areas will likely surpass that of Houston in 2020. That’s right: for 16 years, more than 80 percent of the growth in Harris County has taken place outside of the city limits of Houston and the 34 other cities that make up the county. Already, says the report, “‘Harris County Unincorporated’ would be the second largest city in Texas, the fifth largest in the U.S. and has a larger population than 14 U.S. states.” [Harris County Budget Management Department via Houston Chronicle] Map of populations inside and outside of ring roads: Harris County Population Report – January 2017
