Although 24 counties Total W ithin Incorporated Places Outside Incorporated Places recorded losses both decades in their populations within 3000 incorporated places, 32 experienced gains both decades in this group and 43 counties had one decade of growth and the 2500 other of loss (Table 2, Figure 4). For the counties that 2000 experienced one decade of growth and another of loss, the growth almost always came during the 1990 to 2000 period 1500 followed by a reversal into loss between 2000 and 2010. 1000 In the entire 20 years between 1990 and 2010 the state’s incorporated cities and towns gained nearly 280,000 500 residents while the unincorporated areas lost over 10,000 people (Table 3).
