The following is a comparison of some of the data from the 2000 and 2010 census:
How do we interpret this data? Probably best to only look at trends. A few are fairly clear even if the totals are incorrect: we are getting older. No surprise there. Also no surprise is the total under 19 years of age is getting smaller. That correlates to the declining school enrollment. The booming real estate market at the turn of the century is evidenced by the 12.30% increase in housing units and and the nearly 23% increase in "vacant" units. Much of that activity probably occurred between 2000 and 2008 with a significant drop through 2010.
The average household size was essentially unchanged between 2000 and 2010 at 2.33. There are 104 less households reported in 2010. Multiply that number times 2.33 and you get 242 people. The question I have is whether we truly lost 104 households or were they just not counted? That additional number would make our population about 4,291 ( a 2.84% drop) a much more believable number. Can't prove it without doing another head count, but as I said in the beginning, we need to make decisions based upon data.
The US Census Bureau estimates New Hamphire's 2014 population at 1.327 million up from 1.317 million in 2010 and 1.240 million in 2000. As a state we are growing, but very slowly. Our growth rate is just 0.16% ranking 45th in the country.
