### Sources of Data

Data related to the population can be acquired by the process of collecting, compiling, evaluating, analysing and otherwise disseminating demographic, economic and social data, at a specified time, to all

persons in a country. These are known as sources of population statistics. These sources are classified into two groups; Primary and Secondary.

#### Primary Sources

Primary sources are obtained by witnesses or recorders who experienced the events or conditions being documented. Often these sources are created at the time when the events or conditions are occurring, but primary sources can also include autobiographies, memoirs, and oral histories recorded later.

• Sample surveys
• Census
• Vital Registration
1. Sample Surveys
Sample Survey is the process of selecting a sample of elements from a target population to conduct a survey. The term survey may refer to many different types or techniques of observations. In survey sampling, it most often involves a questionnaire used to measure the characteristics and attitudes of people. It is the process of collecting important data from a selected groups of people that represent the whole population of an area.

2. Census
It is the main source of population data. A population census determines the size of a country's population and the characteristics of its people, such as their sex, background, marital status, income, literacy, religion, language, caste/ethnic group, economically active population, education, number of children, employment status, occupation etc. The first census was taken in 1911 A.D. Nepal observed the centenary of thecensus in 2011 A.D.

A census provides detailed information on different aspects of the population such as its composition, distribution, and change. A census report greatly helps in making realistic future plans.

3. Vital Registration
The most common way of collecting information on this event is through Vital Registration. It is the administrative system used by governments to record vital events which occur in their populations. It also refers to the formal registration and statistical recording of vital events such as birth, death, migration, marriage, abortion, divorce and adoption.

Administrative Records are very vital for an effective plan to manage the population. The administrative record is the paper trail that documents the agency's decision-making process and the basis for the agency's decision. It is a data collected by administrative units like a number of students, telephone directory, records of public servants, health status etc.

#### Secondary Sources

Secondary data refers to data that was collected by someone other than the user. Secondary data are those data which are already prepared and compiled by different national and international organizations for their own purposes. Secondary sources of statistics can be journals, magazines, reports related to different research, annual reports etc. Secondary data can be obtained from different sources such as

• progress reports
• internet searches or libraries
• information collected through censuses of government departments like housing, social security, electoral statistics, tax records etc.
