  2. B.Rule of 50
  3. C.Rule of 70
  4. D.Rule of 35
Deebii fi sababa agarsiisi

Deebii: C Rule of 70

Sababa

According to the textbook, population doubling time is calculated using the Rule of 70, which divides 70 by the population growth rate (r).

Which region of Africa had the highest percentage of its population living in urban areas in 2016 at 62 percent?

  1. A.Eastern Africa
  2. B.Southern Africa
  3. C.Western Africa
  4. D.Central Africa
Deebii fi sababa agarsiisi

Deebii: B Southern Africa

Table 4.10 states that Southern Africa had 62% of its population living in urban areas, making it the most urbanized region in Africa.

Gaaffii 5

Suppose an Ethiopian administrative zone had 4,500 live births in a year and a mid-year total population of 150,000. What is its Crude Birth Rate (CBR)?

  1. A.15 per 1,000 population
  2. B.30 per 1,000 population
  3. C.45 per 1,000 population
  4. D.60 per 1,000 population
Deebii fi sababa agarsiisi

Deebii: B 30 per 1,000 population

Sababa

CBR is calculated as (Total Live Births / Mid-Year Population) * 1,000. Here, (4,500 / 150,000) * 1,000 = 30 per 1,000.

Gaaffii 6
