Aging Index Ranks Metropolitan Areas
America is getting older, as medical science prolongs life expectancy and the fertility rate hovers at or even below the replacement rate. One metric for gauging the nation’s aging is the median age – the age at which one half the population is younger and the other half is older. In 2000, the median age in the United States was 35.3. By 2013, the median age had increased to 37.5.
But the nation’s aging is by no means uniform. Each of the nation’s 52 major metropolitan areas (over 1 million population), got older between 2000 and 2013. However, the difference was substantial, from a relatively small 0.4 years to a more than 10 times larger 4.6 years.
Metropolitan Areas Aging the Least
Nine of the 10 metropolitan areas that have aged the least attracted more residents from other parts of the country than they lost between 2000 and 2013 (net domestic migration data from the Census Bureau annual population estimates). This is consistent with data showing that younger households move more. The Current Population Survey reports indicates that households with householders less than 35 years of age are more than 2.5 times as likely to move between states as those led by householders from 35 to 64. The real competition for migrants between metropolitan areas is for younger households,
