The number of people living in the five-county metro area moved past the 2 million mark earlier this year. Ryan Robinson, the city's chief demographer, told Lawnstarter the area's population breached the 2 million mark at some point during the summer months and was 2,020,452 as of Oct. 1. Austin's population continues to soar, with the Washington, D.C.-based Urban Institute predicting it could grow up to 3.2 million by 2030. What's more, another recent analysis by Lawnstarter of Census data shows the Austin-San Antonio region is seeing such rapid growth, especially in the corridor along I-35 between the two cities, that it is becoming the next Dallas-Fort Worth metroplex in terms of population growth.
