Tanner is another small suburb in King County that has plenty of appeal. This town has a population of just over 1,000 residents, according to Livability. More than 70% of those residents are adults, and the median age is 43. It makes sense that many residents would be of working age, and the per capita income is $58,783. But even though income isn’t among the highest in the state, the cost of living is not too harsh. The index ranks living here as less than 1% over the national standard, according to City-Data. The same source also reports that education inequality is less here than in Washington overall. This makes sense, since the population in Tanner is well-educated. The town also has a lower unemployment rate than the state average, which may also have ties to availability of education.
