Nampa’s estimated population has reached 102,030, making it the third city in Idaho with more than 100,000 residents.

The Canyon County city’s population has nearly doubled since 2000, when it had just under 52,000 people, according to data released Monday by COMPASS, the Treasure Valley’s regional planning association which compiles the estimates.

Nampa trails Boise, population 236,310 and Meridian, population 114,680. Until 2016, Nampa was Idaho’s second-largest city.

Nampa is the largest city in Canyon County, population 224,530, followed by Caldwell, population 58,830.

The population of Nampa grew 3.7 percent between 2018 and 2019, according to the data.

COMPASS updates its population estimates in April each year, using the 2010 Census as its base and uses information like building construction permits, vacancy rates and annexations to pinpoint its estimate.

“A complete count in the 2020 Census will be a key factor in ensuring our annual population estimates continue to be accurate as well,” said COMPASS Principal Planner and demographer Carl Miller in a news release. “COMPASS is already working with local agencies and organizations throughout the Treasure Valley, as well as the US Census Bureau, to help ensure everyone is counted in 2020.”

Idaho was the fastest-growing state in the country in 2017 and 2018, according to the U.S. Census Bureau. Idaho’s population grew by more than 35,000 people to 1,754,208 between July 2017 and July 2018. Ada County’s population also grew 3.6 percent last year.
