New numbers out from the U.S. Census Bureau confirm something you’ve definitely noticed in the last eight years: Clark County is growing fast.

Clark County had the second largest population growth nationwide from 2017 to 2018, increasing by a net of over 48,000 people. Maricopa County in Arizona had the highest numeric growth at more than 81,000 people.

Since 2010, Nevada has seen a net growth in its population of about 280,000, a trend led by both the city’s growing immigrant population and “natural increase” — more births than deaths, making it 5th in the top 10 counties for numeric growth over the past eight years, continuing more than a decade of substantial growth, according to the latest data released by the U.S. Census Bureau.

Harris County in Texas took the top spot in numeric growth from 2010 to 2018 with a population boom of about 605,431.

Nevada wasn’t alone, most of the nation’s population growth in the last year came in counties to the south and west, led by large numeric increases in Texas and Arizona.

The Dallas-Fort Worth-Arlington metro area had a high rate of natural increase, while the Phoenix-Mesa-Scottsdale saw a surge in immigrant residents.

What might seem like disproportionately rapid growth in Southern Nevada reflects a recent trend in other metro areas.

“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,” said Sandra Johnson, a demographer in the Census Bureau’s Population Division in a statement. “Though no new metro areas moved into the top 10 largest areas, Phoenix, Seattle, Austin, and Orlando all experienced numeric increases in population since 2010, rivaling growth in areas with much larger populations. This trend is consistent with the overall growth we are seeing in the south and the west.”

Dallas-Fort Worth-Arlington, Texas, had the largest numeric growth by metropolitan area with a gain of 131,767 in 2018.

Los Angeles County took the top spot for county population, with about 10.1 million people. About 13.0 million people were recorded in the greater Los Angeles metropolitan area, according to the data.

Alaska, Hawaii, Louisiana, Mississippi and Wyoming are among the nine states that saw their populations decline in the past year.

Areas with the largest decreases included all metro areas within Puerto Rico, which was devastated by Hurricane Maria in 2017.

A snapshot of the data from the U.S. Census Bureau has a breakdown of where the country saw the largest gains and losses over the last year.

Additional data for city, state and county population estimates by age, sex, race and Hispanic origin will be released in the coming months.
