This table lists the change over time in population of a small town in France. Between  which two consecutive entries from the table did the rate of population growth change the most? Explain your math.

Context: Historical population
Year	Pop.	±%
1911	752	— 
1962	437	−41.9%
1968	486	+11.2%
1975	398	−18.1%
1982	393	−1.3%
1990	382	−2.8%
1999	395	+3.4%
2008	441	+11.6%

Answer: The rate of population growth changed the most between the entries for 1962 and 1968. Between 1911 and 1962, there was a -41.9% change in population, and between 1962 and 1968 there was a +11.2% change in population. The rate of change of population growth was |(−41.9% - +11.2%)| = 53.1% change, which is larger than the absolute difference between any other two consecutive rows in the table.
