Young, hip Seattle still very short on children

The Seattle Times reports:

There's something missing from many Seattle neighborhoods: the sound of children's laughter.

Recent census data indicate Seattle is continuing a decades-long trend of having the lowest concentration of children among all the major U.S. cities, except San Francisco.

Less than 20 percent of all Seattle households included children younger than 18, compared with 34 percent nationally and 33 in Washington state.

Seattle also has one of the nation's highest rates of married couples without children and one of the highest rates of people living alone.

Great moments in Blue America! It must be progressive because Seattle is such a progressive city. Right?
