Describe and compare between different populations using the population pyramid PERFORMANCE OBJECTIVES Compute and interpret rates of fertility Compute and interpret dependency ratio Compute the rate of natural increase Compute the population doubling time
Age distribution of the Saudi Population in 2000 and 2015 (approximated in million) Activity 3: Age groups Year 2000 Year 2015 Calculate and compare the dependency (years) < 15 8000000 7000000 ratio 15 - < 65 12000000 19000000 65+ 500,000 900,000
Activity 4: The 2015 Saudi population is 27 752 000 with 514 births and 92 deaths. 1. What is the rate of natural increase (considering migration is nil)? 2. What is the population doubling time?
The age distribution of women in the reproductive period and the live births (hypothetical data) Activity 5: Age No. of From the table, what are the fertility Live births ------- groups females indicators that can be computed? 15- 100 8 20- 250 80 25- 200 96 30- 300 84 35- 200 40 40- 150 24 45 49 250 20 Total 1450 352 Total Population = 2750
The age distribution of women in the reproductive period and the live births (hypothetical data) Activity 6: Age No. of From the table, compute the following Live births ASFR groups females fertility indicators 15- 100 8 20- 250 80 1. Crude Birth Rate (CBR) 25- 200 96 2. General Fertility Rate (GFR) 30- 300 84 3. Age Specific Fertility Rate (ASFR) 35- 200 40 40- 150 24 4. Total Fertility Rate (TFR) 45 49 250 20 5. Gross reproduction Rate (GRR) Total 1450 352 [female=48%] Total Population = 2750
