OPTIONAL

If you want to prepare a web page in response to this assignment that would be great. This is not required however.

Questions:

2. In the year 2000, the world's population was about 6 billion people. If the world's population continues to grow at the rate of 1.25% per year, what will the world population be in the year 3000? What will the population be if the growth rate is 0.8% per year.

3. The Following Table shows the population of Oregon Counties from The period of 1950 to 1995. You have just been giving a job as resource manager for the state of Oregon and you need to examine the population base as a function of county within the state. This is your first day on the job and your boss gives you a bunch of data to distill to answer the following questions:

• a) What would the projected population of Lane County be in the year 2020?

• b) What is the fastest growing county (in terms of percentage not raw population) in Oregon since 1960?

• c) Where are the regions of fastest and slowest growth in Oregon. To help you, here is the county map of Oregon:

• d) Compare the growth rates from 1970 to 1980 with those from 1980 to 1990 for Lane and Douglas counties. What do you see and do you have an explanation for this result? That is, was the growth rate the same between decades, higher, lower or what. Finally, how does the Lane country growth rather between 2000 and 1990 compare to that between 1990 and 1980?

• e) Using the exponential growth tool determine the average growth rates from 1950-2000 for the following counties: Deschutes, Jackson, Lane Lincoln, Marion and Multnomah.

4. Below is the data that corresponds to the population by region in the United States:

a). Using this data, estimate what the percentage population of each of these regions will be in the year 2025 and specify how realiable you think your estimate is.

b) show what the difference in your estimates would be if you assume the population is growing (or declining) linearly instead of exponentially.

The Data:

Population Distribution by Region
Expressed as a Percantage of Total US Population
 stratifier 1970 1975 1980 1985 1990 1991 1992 1993 1994 1995 1996 1997 1998 Northeast 24.25 22.93 21.69 20.96 20.4 20.21 20.03 19.88 19.72 19.57 19.42 19.27 19.14 Midwest 27.97 26.87 25.98 24.72 23.96 23.88 23.8 23.73 23.65 23.58 23.5 23.39 23.27 South 31.05 32.29 33.27 34.22 34.37 34.47 34.55 34.66 34.8 34.94 35.06 35.19 35.31 West 17.22 17.91 19.06 20.1 21.27 21.44 21.62 21.73 21.83 21.92 22.02 22.16 22.29

c) Now use this data to estimate what the total US population will be in the year 2025 and what the US population growth rate is:

5. In 1950 the population of India was 357 million and in China it was 555 million.

In 2000 the population of India was 1 billion and in China it was 1.28 billion.

Calculate the respective growth rates for India and China and then determine in what year in the future, based on those growth rates, will the population in India overtake that in China. Course Page
