An article by Nancy Keates in today’s The Wall Street Journal indicates that more than 1,000,000 baby boomers moved to within the downtowns of the 50 largest cities between 2000 and 2010. The article quoted Redfin.com as the source for the claim.
In fact, the authoritative source for such information is the United States Census. The Journal’s claim is at significant variance with Census data.
First of all, according to US Census Bureau data, the areas within 5 miles of the urban cores of the 51 metropolitan areas with more than 1,000,000 population lost 66,000 residents between 2000 and 2010 (See Flocking Elsewhere: The Downtown Growth Story). It is implausible for 1,000,000 boomers to have moved into areas that lost 66,000 residents (Figure).
Secondly rather than flock to the city, as the Journal insists, baby boomers continued to disperse away from core cities between 2000 and 2010, as is indicated by data from the two censuses. The share of boomers living in core cities declined 10 percent. This is the equivalent of a reduction of 1.2 million at the 2010 population level (Note). The share of the baby boomer population rose 0.5 percent in the suburbs, the equivalent of 175,000. Outside these major metropolitan areas, the share of baby boomers rose three percent, which is the equivalent of 1,050,000. All of the net increase in boomers , then, was in the suburbs or outside the major metropolitan areas, while all of the loss was in the core cities.
Among the 51 major metropolitan areas, only seven core cities gained baby boomers (See table at Demographia.). Among these seven, only two had larger percentage gains than the suburbs in the same metropolitan areas. One of these was Louisville, which accomplished the feat by a merger with Jefferson County. Louisville’s gain appears to have been simply the result of moving boundaries, not moving people.
Note: The age groups used are 35 to 55 in 2000 and 45 to 65 in 2010, which approximate the baby boomers. There was a decline in the number of baby boomers between 2000 and 2010 (largely due to deaths). The figures quoted in this article allocate the same percentage loss from this reduction to the 2000 baby boomer population for each core city and metropolitan area (the national rate).
