Census, a source of population data

Census is the main source of population data. The census is the enumeration of people, house, firm, offices and other important institutions in a country.

It is taken in frequent intervals that may be every 10 years (in many countries), every 5 years or at irregular years. UN (1970) has defined census as- A population census may be defined as the total process of collecting, compiling, evaluating, analyzing and publishing demographic, economic and social data pertaining at a specified time to all persons in a country or well specified territory.

Method of census

Census is carried out in two major ways:-

1. De facto method      2. De jure method

i.            De facto method     

In this method of census, a person is enumerated in the place where s/he is at the time of collecting. Usually a dated is fixed by the government as a “census day” and people are pre-informed about it. As all people are found in their home at night census is done at night. So, it is also called as “one night enumeration”. It is practiced usually in the developed and urban region.

ii.            De jure method

The census method that is conducted on the basis of permanent place of residence is called de jure method. This method of census is more practical and scientific. Usually a period of 2 to 3 weeks is kept for the enumeration. It is common in rural and less developed regions.

Sources of Population Data

Population data denotes the index which gives the various information of population like birth, death, migration, age, sex, marital status, religion, occupation, etc. Such data help to formulate and implement the various policies and planning in a country.

Population data can be found from various sources. On the basis of the nature of the data, they can be broadly divided into two groups.

1. Primary sources
2. Secondary source

1. Primary source

  First hand data which are collected from the top level sources which are census, vital registration, administrative record, population registration, etc.

2. Secondary sources

  The data are found from person, organization, agencies, books, journals, magazine, annual reports, etc which are lower level data.

World population was 6.6 billion in 2007. Developing regions share more than 80 percent (5.4 billion) of world population. World population growth was 1.2 percent in the year 2007. World population will reach 7 billion in 2010/11 and about 9 billion in 2050. Asia only shares about 60 % (4 billion) world population. About half of the population in the world lives in urban areas. Developing region had lower life expectancy and higher IMR in comparison to the developed region. This has caused a huge gap in the quality of life of people living in developed and developing nations.

Going Green...

Lets make our planet better

 

Lets join our hands together for a green and a better planet. 

Go Green- for global warming, for pollution, for wildlife and for our planet. 

World population will be reaching 9 billion by 2050. With this limited natural resources with us, it is impossible to meet the demand of people  in future. So, take the initiatives today to help conserve our resources and build a better planet for tomorrow.

It is today that will make a good future for our children. 

 

What is Population?

Population denotes the total number of children, youth, adult and old people residing in a particular place within  specified time. In other words, population is total number of people residing in a particular area in a specific time. The group of people are attached with their own racial, social and cultural values and norms.

Situation of World Population Today...

Except few developed countries most of the other countries in the world are facing the problem of high population growth.World population is growing fast and it has exceeded the limit that the resources of earth can bear.

World	6.555	21	52	2.7
Asia	3.968	20	49	2.4
Africa	0.924	38	84	5.1

Trend of Population Increment......

Human beings are supposed to have evolved 3 million years ago. At the time of beginning of agricultural era, the size of population was 250 million. In 1850 it reached 1 billion. Since then the rate of population growth is alarming. Similarly it reached 2 billion in 1980 and 4 billion in 1975. It rose up to 5 billion in July 11, 1987. Therefore July 11 is celebrated as "World Population Day". In October 12 of 1999, world population reached 6 billion and this day is celebrated as "The Day of Six Billion". By 2011 world population will reach 7 billion. Now the world population is gaining 3 persons per second and 810 million per year.
