One obstacle to assessing the direction of the American economy is the difficulty in getting a handle on how many people live in this country and how fast that number is growing.\xa0 It would seem to be a very elementary problem \u2013 surely the Census Bureau provides timely data on the size of the population, as well as births, deaths and net migration?\xa0 But it does not.\xa0 So far as I know, there is no official consistent measure of any of these numbers on a monthly, (or for that matter an annual basis), going back over the decades.\xa0 Moreover, the last time the Census provided a projection of the future path of these vital statistics was back in 2017.
