Give two primary sources of population on data.

KCSE Geography Paper 2 2003 Section B Question 7.

​a) i) Give two primary sources of population on data.

• National census head count
• Sample survey
• Vital statistics / registration of birth / death / marriages / migration.

​ii) What information can be derived from a population pyramid?

• The  size of the population
• The different age cohorts(age groups)
• The proposition of males to females.
• The composition by sex.
• The proportion of the youthful/working / ageing/ dependency ratio.

​b) Describe three ways in which the population of Kenya differs from that of Sweden.

• The population of Kenya has a large number of young people below 20 years of age while Sweden has an ageing population.
• Kenyans population has a lower life expectancy while Sweden has a lower life expectancy.
• Population birth rate in Kenya is high while it is low in Sweden
• The fertility rate in Kenya is high while in Sweden
• The population growth rate is high in Kenya and low/negative in Sweden.
• A high percentage of the population in Kenya live in rural areas while in Sweden most people live urban areas (the difference must be complete)

​c) Explain four reasons of rural migration in Kenya.

• Pressure on land makes people buy/look for land elsewhere and move to settle there.
• People move from the rural areas makes people to move to safer places
• Setting up of government development projects cause displacement of people who are settled elsewhere such projects cause displacement of people who are settled elsewhere such projects attract settlements in those areas (settlement schemes)
• Natural hazards force people to migrate to other areas for safety 
• Pastoral communities migrate from one rural areas to another in search of pasture / water for their livestock
• Change in land tenure system/ and disputes cause people to move and settle elsewhere.

​d) Explain three problems, which result from the high population growth rate in the East African countries.

• The rate of population growth is higher than the rate at which job opportunities are generated leading to high unemployment.
• The high demand for social amenities caused by the high population growth rate leads to congestion in schools /hospitals/ housing/transport facilities.
• The large number of youthful population create a high dependency ratio which causes slow economic growth.
• The high demand for food caused by the high population growth rate has lead to food shortage
• The high demand for agricultural land cause land fragmentation. 
• The large number of poor people /unemployment lead to temptation to commit crime/high crime rate
