If the experts are right, some time this month, perhaps somewhere in the suburban South or West, a couple, most likely white Anglo-Saxon Protestants or Hispanic, will conceive a baby who, when born in October, will become the 300 millionth American.

As of yesterday, the Census Bureau officially pegged the resident population of the United States at closing in on 297,900,000. The bureau estimates that with a baby being born every 8 seconds, someone dying every 12 seconds and the nation gaining an immigrant every 31 seconds on average, the population is growing by one person every 14 seconds.

At that rate, the total is expected to top 300 million late this year. But with those projections adjusted monthly and the number of births typically peaking during the summer, the benchmark is likely to be reached about nine months from now.

"You end up with a number in October," said Katrina Wengert, a demographer and a keeper of the Census Bureau's official Population Clock, getting about as specific as possible this far in advance in a field subject to chronic fudging and revising. The clock is, itself, a contrivance, of course, but no more so than other pretexts for a wintertime sexual encounter. Rest assured that hospital publicists, canny obstetricians, entrepreneurial chambers of commerce, baby food manufacturers, public officials and countless others pursuing some political social or personal agenda, abetted by the media, are already guesstimating the growth rate to anoint any number of unsuspecting newborns as the mythical American who pushed the nation's population to 300 million.
