A population can be defined as the total number of all the organisms of a same group or species living in a particular geographical area. The population is the total number of people living in a particular place like village, city, country etcetera at a particular time. The population of any area does not remain the same, it keeps on changing with respect to time, environment, fertility, mortality and migration. We can estimate the size of the population of a particular place at a particular time.

#### Population Size and its Growth Rate

The current population of the world is 7.4 billion according to the 2016 survey. It is the highest of all. The population of the world is increasing day by day. China covers 18.79% (according to a survey conducted on June 20, 2016, AD) of the World with the highest population in the world. The country with least population in the world is Vatican City with 839 people according to the survey conducted on July 1, 2012, AD. Talking about the history of the population of Nepal, the first census was conducted in 1911 AD until 1940 AD but, it was not systematic. But in 19525/52 AD, the census was conducted using internationally acceptable definition and methodology. But only the census of 1961 AD is accepted as the first scientific census of Nepal in terms of international standard and comparison. The given table present the total number of population from the census since 1911 AD.

In the above-given table, we can observe that the population of Nepal was decreasing up to 1930 AD. The population of Nepal was in decreasing phase from 1911 to 1930 AD. The population of Nepal in 1911 was 5.6 million whereas in 1920 the population decreased to 5.5 million. The population in 1930 was less than the population in 1920. It is believed that the reason behind the decreasing trend of this population was worldwide influenza epidemic, famine, unscientific census and heavy casualties suffered by Nepalese Army in the First World War. The census of 1920 was conducted after the First World War and the census of 1941 AD was conducted during mid- period of the Second World War in which about 2,00,000 Nepalese soldiers were recruited in the Gurkha Army. The census of 1930 AD was conducted during the time when Nepal was preparing for war with Tibet. Other reasons may be undercounting of the population during those censuses because the census enumeration prior to 1952/54 AD used to be conducted by landlord's agent. This census lacks scientific and systematic methodology and trained and supervised persons who carried out the calculation.

Some reason of decrease in the population in the second and the third census are listed below,

• First World War
• Recruitment of Nepalese Youth to Gurkha Army
• Unscientific and unsystematic methods of counting population
• Famine for long period
• Spread of pandemic Influenza
• Due to Nepal- Tibet War

The population of Nepal started increasing from 1941 AD onwards. The population increased by 2.27% during census period from 1941 to 1952. The population of the Nepal increased by 1.64% from 1952/54 to 1961 AD. The population growth rate has crossed 2% since from 1971 to 2001 AD census. The population growth rate was 1.35% from 2001 to 2011 AD.
Here, the main reason for the increase in population was less mortality rate with persistent high fertility rate, the return of Nepalese from I and II World War and from other countries after the establishment of democracy, less spread of pandemic diseases, immigration in large number from neighboring countries like Bhutan, India, etc. The population growth rate was stable in 2011 AD as it was 1.35%. If the population of our country goes on increasing like this, the population of our country will be double in coming 52 years.

Some of the reasons for rapid increasing of population after 1941 AD are listed below,

• Marriage at young age
• High infant mortality rate
• Low status of Women
• Importance to son
• High fertility rate
• Immigration
• Polygamy
• Poverty
• Superstition
• Joint family
• Lack of family planning

According to the population census report of 2011 AD, the demographic status of Nepal is given below,

Average population growth rate: 1.35%
TFR: 2.6
CBR: 24.3
IMR: 46
CMR: 54

This demographic data of 2011 AD is better than other censuses. As we know that, the population growth rate was less from 2001 to 2011 AD than other censuses. Education, an increase in contraceptive prevalence rate, foreign employment, public awareness, woman empowerment, the tendency of late marriage, attraction to the small and nuclear family were the reasons behind the fall of population growth rate. Some reasons behind the fall of population growth rate from 2001 AD to 2011 AD are listed below,
