The village continued to grow steadily for the remainder of the 1960s, reaching a population of 7,000 by 1970. The 1970s were the first period of rapid growth in Bolingbrook, during which its population quintupled to reach over 37,000 by 1980. Much of this growth was as much due to mass annexation as well as raw population growth; the population of Bolingbrook by the 1970 census but with its 1980 land boundary was approximately 25,000, further reflecting the vigorous annexation that took place during the 1970s.
