Population and Housing Census [hh/popcen]
The Population and Housing Census 2011 is the eleventh round of population census history of Nepal. It is also marks 100 years of census taking in Nepal.
The objectives of the 2011 Population Census were:
a) to develop a set of benchmark data for different purposes,
b) to provide distribution of population by demographic, social and economic characteristics.
c) to provide data for small administrative areas of the country on population and housing characteristics.
d) to provide reliable frames for different types of sample surveys,
e) to provide many demographic indicators like birth rates, death rates and migration rates.
f) to project population for the coming years.

National Population and Housing Census 2011 uses two schedule for data collection. The short form (schedule 01) for the complete enumeration of the benchmark information and the long form (schedule 02) for the sample enumeration of other socio-economic and demographic information. The long form was administered for population dwellings in about 20 percent of the total housing units. Based on these, estimates were generated at the district level with reliable degree of precision.
The sampling scheme of the 2011 Population Census for the long form is summarized below.
1. The sampling covered the private households only. For the institutional population, Schedule-1 only was administered.
2. For the sampling, 75 administrative districts formed the main strata and VDC's and municipalities within the district formed the domains.
3. There were around 36,000 wards in the country at the time of the census. For the purpose of the census enumeration some of the large wards were further divided into sub-wards. These wards and sub-wards formed the EA's for sampling. The total number of EAs thus formed were around 40,000.
4. Sampling was carried out in each EA; housing unit being the sampling unit.
5. The list of housing units and households served as the sampling frame for the EA. The housing units were selected by systematic sampling method. The sampling interval taken was 8.
6. The list of selected housing units was made available to the enumerator for the enumeration. All households and persons found in the selected units were enumerated.
7. The ratio method was used in making estimates for the sample.
8. Tabulation groups were created separately for tabulation of persons and those for households. The main control variables for the majority of tabulations for persons were two variables: age sex. Tabulation groups for household tabulations were formed in a different manner: taking households as a tabulation group in the domain.
9. To implement the ratio estimation, first weights were calculated. The weights for sample data were computed by dividing the 100 percent counts for the same tabulation groups in the domain by sample counts for the same tabulation groups in the domain. To avoid inconsistency due to rounding, the figures were converted to whole numbers.
This detailed sampling procedure is documented in the Technical Documents.
At the time of census there were 3,914 VDC's and 58 municipalities. VDC's contained a total of 35,226 wards while urban areas contained 806 wards. Thus total numbers of wards in the country were 36,032. All households and individuals from the total wards are counted at the census. However, the post enumeration survey shows that about 3.5% population are under enumerated.
Sample scheme is used in National Population and Housing Census(NPHC) for the first time in 2001. The same concept is continue in National Population and Housing Census (NPHC) 2011. The procedure of sample selection of housing units in each enumeration area (EA ) is systematic sampling design. Systematic sampling is carried out for all general households ( excluding institutional households) by first computing the sampling interval which is equal to 1/f (1/8). The selection within each EA was carried out by the census supervisor and enumerated by enumerators.
The Sample Design for canvassing Form 2 in selected households was Single Stage Systematic Sampling. Such a design is generally very convenient to implement and errors in selection can be easily detected.
The ratio estimation method is used in making estimates from the sample. It ensures that the sample estimates are generally consistent with the 100 percent counts and the estimates have smaller sampling errors.
Dates of Data Collection
Data Collection Mode
Eighty Census Officers and eighty Area Census Supervisors were recruited by the CBS and 7,909 Field Supervisors were recruited for direct supervision to the enumerator.
Data Collection Notes
EA Maps : Enumeration Area maps (EA) is prepared for all urban areas and some of large VDCs since fiscal year 2008-2009, two years before the census
Pre-Test : Pretesting of the census questionnaire was conducted in the Kathmandu valley, surrounding districts and in the rural part of the Tarai
Pilot census : the pilot census was conducted in seven districts (Jumla, Doti, Banke, Kathmandu, Syangja, Mahottari, and Ilam) to ensure familiarisation with all census procedures. Altogether, 10,000 households were interviewed in seven districts.
Census publicity: All national dailies, weekly papers, magazines,TV channels, and radios carried census messages to the public throughout the period of the fieldwork.
Training : Various levels of training were organized for different levels of staffs in the census at different points of time. These included the training of the master trainers, district census officers, area supervisors, field supervisors and the enumerators. To start with, a group of master trainers were trained in the Bureau. The master trainers together with the Mainstreaming Gender Equity Programme (MGEP, an UN-agency) staffs, and the Sahavbagi, a leading NGO, also participated and facilitated the central and district level training of the census field staffs. These training were mainly focused for maintaining uniformity on the census procedures, terms and definitions used in the census questionnaires and developed understanding among all the trainees.
Enumeration : 30,793 census enumerators and 7,909 supervisors are directly involve in enumeration and supervise.
Modified de-jure method is applied.
Interviews averaged 35 minutes for the household questionnaire. Interviews were conducted primarily in Nepali.

Two types of schedules were prepared. Form 1 for complete enumeration and Form 2 for sample enumeration. Both schedules contained questions on household as well as individuals.
FORM 1: (COMPLETE Enumeration)
A. Household Information (Question relating to Household), Type of house ownership, type of foundation, type of outer wall, type of roof, main source of drinking water, usual type of fuel used for cooking, usual source of lighting, toilet facility, household facilities, Female ownership on house, area of land owned by female member, death occur during the last 12 months, sex, age of deased person and cause of death, Absentees from Household (HH), reasons & country of destination.
B. Individual Information (Question relating to Individuals), Name, sex, age, relationship to the Household head, Caste/ethnicity, marital status, age at first marriage, religion, Language spoken, citizen, disability, literacy status, level of education.
FORM 2: (SAMPLE Enumeration)
A. Individual Information (Question relating to Individuals), Place of birth, years of staying, reason of staying, place of living before 5 year, Children ever born, live births during the last 12 months, Usual activity during the last 12 months (economic/non-economic activities), occupation, industry, employment status, reasons for not being active, living arrangement of children below 16 years of age.
Data editing and cleaning take place in various stages:
a) Coding is done for open ended questions like Caste/Ethnicity, Mother tongue, Second language, Cause of death, Country of destination, Citizenship, Occupation and Industry etc. by
b) Data entry application was developed with comphrehensive logic to capture miskeying as well as intra-record and inter-record inconsitencies. CSPro software is used to develop
data entry application for data capturing.
c) Structure checking and completeness check upto ward level. CSPro Batch edit program and SPSS programm is used to check structure checking and completeness check.
d) hot deck and cold deck techniques are used in second stage of data editing and cleaning. CSPro Batch edit program is written to address automatically where inconsistencs and
anomalies are found.
e) 10% sample questionnaires are re-entry to control miskeying.
Approximately six hundred data processing staff, plus experts, are involved in coding, editing, key entry operations and verification. CSPro, an integrated software developed for data entry, editing, verification and tabulation was used for data processing (key entry, editing and verification). SPSS and STATA software package are used for tabulations.
The field work of the Post Enumeration Survey (PES) was conducted in September 2011, three months after the main census. The sample size for this survey, owing to time constraints, was fixed at 10,000 households. enumeration rate was estimated to be around 3.63% in the census of 2011 compared to 5.3% in 2001.
