DEFINITION OF POPULATION CENSUS

Population Census- may be defined as a systematic enumeration of all nationals of a country at a given period of time irrespective of the person’s nature. Census is usually carried out once in every ten (10) years as in the case with Nigeria. The last and the most recent census was held in the year 2006, March 21 – 25. Therefore, the population of a country will include the nationals living in the country excluding the non-nationals (foreigners) living in the country plus nationals living in other countries.

FORMS OF POPULATION CENSUS

Two basic forms or method or approaches is adopted in counting the number of people (census) in any country. They are:

  1. De-Facto Method: this is the method of counting people who are physically present wherever they can be found
  2. De-Jure Method: This is a method in which persons who are regular residents in a particular place are counted. This method counts people in proxy that is the head of each family or whoever is available will enumerate and provide information on members of the family. This is not an ideal method of population census.

EVALUATION

  1. Define population census.
  2. Explain the two types of population census.

IMPORTANCE OF POPULATION CENSUS

  1. Census is used to determine the size and rate of growth of the population.
  2. It enables the government to obtain adequate basis for economic planning and policies
  3. It is used to determine the per capital income (PCI) of a country vis-a-vis the standard of living.
  4. It provides relevant data for the distribution of a country’s resources. (Revenue allocation )
  5. It influences the magnitude of the flow of grants, aids and investments into a country.
  6. It forms the basis for the importation of goods and services.
  7. It help demographer to determine future forecast.
  8. Within each country, the census is used to distribute parliamentary seats i.e. for political use.

PROBLEMS OF CONDUCTING CENSUS IN NIGERIA (WEST AFRICA)

  1. High cost of conducting a census
  2. Shortage of trained census personnel (man power)
  3. Poor and inadequate infrastructure preventing accessibility
  4. Prohibitive customary and religious beliefs
  5. High degree of illiteracy
  6. Bad town Planning
  7. Economic benefits and political problems
  8. Superstition —ill-luck to family by counting their children

EVALUATION

  1. What are the problems of conducting census in Nigeria.
  2. List five importance of conducting population census.

POPULATION DISTRIBUTION

Population distribution is the way in which the population of a country is distributed into different categories such as: Age, Sex, Occupation and Geographical.

AGE DISTRIBUTION

This is the number of persons in different age groups in the population. In other words, it shows the number of people in different age groups e.g. 0-5, 6-10, 11-15 etc.

However for some analysis, such as the labour force, the population is broken into:

0 -15 years: the dependent population

16 – 60 years: the working population or labour force

Above 60 years: the dependent population

The first group is made up of infants, 0-15 years. This group is unproductive and they depend on the working population for survival.

The second group 16 – 60 years (which may be extended or reduced by different countries) is the most productive group and it supports the first and the last groups. It is the working population or the labour force. The last group 60 years and above is made up of men and women who are no longer economically productive but are dependent on the working population .

The age division varies among countries but whatever the variation; the dependent and the working population should be easily differentiated

SEX (GENDER) DISTRIBUTION

Sex distribution shows the relative proportion of males and females within a given population. The sex ratio is used to indicate the sex distribution which is defined as the number of male in the population per 1000 females.

If there are more women than men in the population, a higher birth rate should be expected. The size of the labour force will be equally affected.

In some African countries, women by customs are not allowed to work and this practice would affect the labour force.

EVALUATION

Write short note on

  1. Age distribution.
  2. Sex distribution.

OCCUPATIONAL DISTRIBUTION

This refers to the division or spread of a working population in to the types of job or occupation they do. This distribution is affected by the available natural resources, level of education and technological development.

GEOGRAPHICAL DISTRIBUTION

This refers to how people are spread over a given geographical area in terms of where they live. This is necessary because there is more concentration in some area and less in others, that is, high and low population density. This situation arises due to a number of factors such as;

The Climate

Employment opportunity

Nature of soil

Social and historical factors

DEPENDENCY RATIO

This is the ratio of the dependent population simply called dependants to the working population. If the number of dependents is higher than the labour factor, then the ratio will be high and vice-versa. That is to say, the standard of living of the workers will be low since they have to spend much money to cater for those unproductive age groups. The dependency ratio is represented by this formula

Dependency ration = Total Dependent Population / Total Working Population

Worked Example:

Find the dependency ration from the table given below:

Age Group                                                     POPULATION

                                                                                    (000)

0 -16                                                                            16

17 – 35                                                                        22

36 – 60                                                                        43

Above 60                                                                    14

Solution

Dependent Population            = 16 + 14 (000)

                                                = 30,000 people

Working Population    = 22 + 43 (000)

                                    = 65,000 People

Dependency Ration     = 30,000/65,000

= 6/13

= 6: 13

EVALUATION

  1. Define population density.
  2. State the formula for calculating dependent ratio.
