PPH4804 ASSIGNMENT 1 2026
DUE 28 APRIL 2026
Introduction
Population studies are important because they help governments plan for reproductive
health and make better public health decisions. Good population data helps countries
decide where to send resources, track health problems, and understand changes in
birth and death rates.
This work looks at where population data comes from, how to improve the accuracy of
census results, and a review of Thomas Malthus’ ideas about population growth. It also
explains why birth and death rates change during the five stages of population change.
The discussion uses examples from South Africa and other countries to show how
population trends affect reproductive health.
Question 1
1.1 Identify and explain the main sources of data (10 marks)
The main sources of demographic data are population censuses, vital registration
systems, sample surveys, and administrative records. Each source provides unique
strengths and limitations for understanding population dynamics.
A population census is a complete enumeration of all persons in a defined territory at a
specific time. It collects data on age, sex, fertility, mortality, migration, and household
characteristics. In South Africa, Statistics South Africa (Stats SA) conducts censuses
every ten years; the 2011 Census and Community Survey 2016 form the base for mid-
year estimates (Statistics South Africa, 2018). Censuses provide benchmark data for
planning but are expensive and occur infrequently.
The vital registration system records all births, deaths, marriages, and divorces
continuously. It supplies reliable fertility and mortality indicators. South Africa’s
