A steady growth
rate of say 1.5% a year, means that the growth in actual population per year will also rise over time.
For example growth rate 1.5% each year
Year 1: 3,000,000
Year 2: 3,045,000 (growth of 45,000)
Year 3: 3,090,675 (growth of 45,675)
Year 4: 3,137,035 (growth of 46,350)
Year 5: 3,184,090 (growth of 47,055)
...
Year 10: 3,430,169
Year 11: 3,481,621 (growth of 51,452)
At this relatively low growth rate, the city is adding 2,055 more per year than it was years previous, in ten years that steady growth rate yields 6155 more people a year than in year one.
Growth rates ebb and flow, but when you average over time, populations grow more or less in an exponential way.
