The 2020 U.S. growth rate of 0.7 percent per year during the preceding decade was the slowest decade of growth since the 1930s. In the absence of sufficient immigration, the total U.S. population is expected to decline. On the surface, this could seem to have some positive impacts such as reducing environmental stresses and other unwanted consequences of overcrowding.

• 2088

Population growth is typically taken by subtracting the births of the population minus the deaths. In other words, you take the __________ and subtract the __________, divide that number by 1000, and multiply that by 100 to turn the growth rate into a percentage.
