2 ACQUISITION OF CITIZENSHIP CERTIFICATE IN NEPAL ESTIMATION AND PROJECTION PREVIOUS STUDY With the objective of mapping and estimating the size and presence of the population lacking citizenship certificates in Nepal, a study was conducted in 2013. The study was based on a review of prevalent data sources and records. Methodology The first step was to calculate the total effective population of Nepal. For the purpose of the study, the total effective population was taken as the population of Nepal above the age of 16 years. This definition was chosen as 16 is the age at which a person becomes eligible to acquire a citizenship certificate in Nepal. • The population of those above the age of 16 for each district in Nepal (A) was taken from the 2011 Census. This figure did not include the migrant Nepalese population but includes foreigners residing in Nepal. • The total number of migrant Nepalese population (B) for each district was also taken from the 2011 Census, and it was assumed that these migrants consisted only of those above the age of 16. • The total number of foreigners residing in Nepal for each district (C) was also taken from the 2011 Census. • The ratio of inter-district migrant Nepalese population for each district (D) was taken from the Population Perspective Plan (Hereinafter PPP) 2010-2031. In the diagram below the symbol (plus +) stands for inter-district migrant population and minus (-) for the incoming population in each district. The relevant eligible population or the population above the age of 16 (E) was then calculated for each district, according to the formula indicated below: Population of 16 years or above that currently reside in the country (A) Migrant Nepalese population (B) Foreigners residing in Nepal (C) Inter-district migration (D) Total effective population (E)
