Issaquah, long ranked among the fastest-growing cities in Washington, is no longer experiencing a population boom, but the city continues to add residents.
The latest tally from the state Office of Financial Management indicates Issaquah added 256 people last year. The estimated population is 30,690 — about 170 percent more people than a decade ago.
The state used data from the 2010 Census as a baseline, and then estimated population for Issaquah and other Washington cities by using information related to school enrollment, housing construction and driver licensing.
State officials use the population data to determine how to allocate dollars to municipalities.
State demographers released the data June 30. The figures represent population changes between April 1, 2010, and April 1, 2011.
Issaquah added 104 housing units during the past year, to bring the total to 14,018 units.
The city spent most of the past decade near the top of the fastest-growing cities list, but the recession slowed housing construction and migration.
Kent — estimated population 118,200 — ranked as the fastest-growing city in Washington last year. Neighboring Sammamish — 46,940 — ranked No. 6 on the list and Bellevue — 123,400 — claimed the No. 8 spot.
Bellevue is also the fifth-largest city in the state. Issaquah holds the No. 36 spot. Seattle — estimated population 612,100 — remains the largest city in Washington.
Unlike the decennial census, state demographers estimate a total. The census is more accurate, because the U.S. Census Bureau sends forms to every household and conducts a door-to-door survey for the count.
The state’s pre-Census 2010 figure for Issaquah estimated the city’s population at 27,160 residents — 3,274 fewer than the census counted. Federal officials released the census data in February.
Data released after the census indicated the city’s population crested at 30,000 people — a sharp uptick from the 11,212 Issaquah residents in 2000. Construction and annexations contributed to the decadelong population boom.
