Project: City Growth
Por sewi Chapter
OBJECTIVE Compare the growth of the city where you live to cities in other
parts of the country.
MATERIALS paper pescil. graphing calculator or computer (optional)
ESTIGATION Different areas of the country grow at different rates. Which region do you
think is growing the fastest? Do you think big cities grow faster than small
Collect data on the population of five cities in 198) 1940, 2000, 2010 and 2020.
Lociode the closest to where you live as well as one city in each of the fol-
Towing regions of the United States south portheast, midwest, and west coast.
Loclade at least one large city (more than 2 million people). one small city
(about a half million people), and a small town (less than 100.000 people)
1. Assuming exposential growth, use the 1990-202 data to write an
exponential equation for the population y of each city z decades after 1980.
2 Use your equations to predict the population of each city in the year 2030,
Compare each to the actual data. For which cities does the equation give a
