As the New Hampshire Municipalities Map illustrates, some counties have smaller populations than towns in others.

Since the mid 1700s the population growth in New Hampshire has been dramatic, at a nearly exponential rate. The earliest data comes from 1767 when the population was 52,672. The next 20 years doubled it and another 25 years produced a total of 214,201 inhabitants in 1810. From there on the growth rate dropped and it took one hundred years to reach 430,376 in 1910. Over the next 80 years New Hampshire passed the one million mark in 1990 when the population totaled 1,109,117. The last two decades have added only about two hundred thousand people to the NH population.
