Historical population change The table and chart, taken primarily from historical data from the
U.S. Census Bureau, shows the population of Hollis from 1767 through 2010. After nearly doubling in population over the last 33 years of the 18th century, Hollis' population consistently declined (excepting only the decade of the 1850s and the first decade of the 20th century) for 120 years, not returning to the levels of 1800 until sometime during the 1950s. Since 1930, Hollis' population has consistently grown, particularly during the 1950s, 1960s, and 1970s. == Culture ==
