Baltimore County Is 3rd Largest County In Maryland: Census

BALTIMORE COUNTY, MD — More than half of U.S. counties grew between 2017 and 2018, according to new population estimates for 2018 released by the Census Bureau. On the contrary, Baltimore County actually lost residents.

According to the Census estimates, Baltimore County lost 172 residents between July 1, 2017, and July 1, 2018. Its population changed from 828,603 in 2017 to 828,431 in 2018.

The decline was due to domestic migration, according to census data.

Even though its population declined year over year, Baltimore County remained the third most populous jurisdiction in the state in 2018, the same slot it held in 2017.

Here are the 10 most populous areas in Maryland in 2018, based on census estimates:

“One interesting trend we are seeing this year is that metro areas not among the most populous are ranked in the top 10 for population growth,” Sandra Johnson, a demographer at the Census Bureau, said in a press release.

These are the top 10 metropolitan areas for numeric growth between 2017 and 2018:

1. Dallas-Fort Worth-Arlington
2. Phoenix-Mesa-Scottsdale
3. Houston-The Woodlands-Sugar Land
4. Atlanta-Sandy Springs-Roswell

On the metro level, the Dallas-Fort Worth-Arlington area had the largest numeric growth in population in the U.S., followed by the Phoenix-Mesa-Scottsdale area. A natural increase in population — having more births than deaths — was the largest source of population growth in the Dallas area, while domestic migration was the largest source for the Phoenix area, the Census Bureau said.
