While I agree with what FSD has said, we need to be alittle carefull in equating populations. Population demographics are not the same between those moving in and those moving out. Immigrants tend to live more to a house/apt than Americans, so demand is not necessary rising just because population is. Number of households may be a better indicator of overall housing demand than total population. I dont know where to get total number of households, I am sure it is in the gov data, but I dont care to spend much time looking.
