2011 Nepal census
The National Population and Housing Census 2011 was the eleventh decennial census in Nepal's history, conducted by the Central Bureau of Statistics to enumerate the country's total population of 26,494,504 as of the official Census Day on June 22, 2011.[1] Fieldwork spanned June 17 to August 25, 2011, marking the centennial of systematic census-taking in Nepal since 1911.[1] The census recorded 5,427,302 households, an annual population growth rate of 1.35% from the 2001 baseline of 23,151,423, and a sex ratio of approximately 94 males per 100 females, with females comprising 51.5% of the total.[1] It employed a modified de jure methodology supplemented by de facto enumeration in challenging areas, using a short schedule for complete population coverage and a long schedule for a 4.2% sample to collect detailed data on demographics, ethnicity, mother tongue, literacy, marital status, migration, disability, and housing characteristics.[1] Urban residents accounted for 17% of the population (about 4.5 million), concentrated in areas like Kathmandu Valley, while 83% lived rurally, reflecting Nepal's predominantly agrarian and topographically diverse terrain.[1] Literacy stood at 65.9% for those aged five and older, with male rates at 75.1% and female at 57.4%, underscoring persistent gender disparities amid overall progress.[1] The operation faced logistical hurdles in remote Himalayan and Terai regions, compounded by political instability and security issues, yet achieved broad coverage through national funding (98.5%) and a workforce with 40% female enumerators.[1] Key outputs included insights into Nepal's ethnic mosaic—over 100 groups—and socioeconomic shifts, informing policy on development, federal restructuring, and resource allocation in a nation spanning altitudes from 70 to 8,848 meters.[1]Background and Planning
Historical Context
Nepal's population census tradition originated with the first national enumeration in 1911, conducted through traditional head-counting methods under the Rana regime.[2] This initial effort established a decennial rhythm, with subsequent counts in 1920-1921, 1930-1931, and 1941-1942, though these pre-independence exercises often suffered from incomplete coverage and reliance on administrative records rather than systematic fieldwork.[3] Evidence from historical records indicates potential undercounts in these early phases, attributed to logistical challenges in remote terrains and limited central authority.[4] The shift to modern scientific approaches occurred with the 1952-1954 census, the first to employ de jure enumeration principles and structured questionnaires following Nepal's democratic transition and international assistance from the United Nations.[5] This marked a departure from ad hoc counts, enabling more reliable data on demographics, housing, and migration. Subsequent decennial censuses in 1961, 1971, 1981, 1991, and 2001, overseen by the Central Bureau of Statistics (established in 1959), documented accelerating population growth—from 8.4 million in 1952-1954 to 23.2 million in 2001—driven by high fertility rates and improved survival amid economic development and health interventions.[6][7] By the early 2000s, these censuses had become foundational for national planning, informing resource allocation and policy amid urbanization and ethnic diversity. The 2011 census, as the eleventh in the series, coincided with the centennial of Nepal's census history and addressed data gaps from the 2001 enumeration, particularly in conflict-affected regions where the Maoist insurgency (1996-2006) had disrupted prior fieldwork.[8][1]Preparation and Objectives
The National Population and Housing Census 2011, the eleventh in Nepal's series and marking a century since the first in 1911, was prepared under the Central Bureau of Statistics (CBS) within the National Planning Commission (NPC).[1] Preparatory activities commenced in 2007, supported by the enactment of the Census Act 2011, which provided legal framework for data collection and enforcement.[1] A multi-tiered committee structure oversaw planning, including the Census Steering Committee and National Census Coordination Committee, both chaired by the NPC Vice-Chairman; the Technical Committee, led by the CBS Director General; and district-level coordination committees chaired by Chief District Officers.[1] These bodies coordinated with ministries and statistical agencies to address logistical needs, with technical assistance from UNFPA and UN Volunteers, and a total budget of NPR 2.2 billion allocated for operations spanning 2007/08 to 2012/13.[1] Key preparatory processes included cartographic mapping from 2008 to 2010, utilizing satellite imagery, GPS, and GIS to delineate enumeration areas across 3,915 Village Development Committees and 58 municipalities, followed by field verification.[1] Household listing operations occurred in October–November 2010 to establish sampling frames, while a pilot census tested methodologies in 11 districts during April–May 2010.[1] Training programs trained approximately 150 master trainers in January–February 2011, who in turn prepared 80 district census officers, 7,900 supervisors, and 30,793 enumerators through phased sessions up to June 2011, emphasizing inclusivity with over 40% female enumerators and representation from diverse castes and ethnicities.[1] Publicity efforts involved media campaigns via television, radio, newspapers, and a dedicated census website to build awareness and cooperation.[1] The census's objectives centered on generating benchmark demographic, social, economic, and housing data to inform national planning, policy formulation, and evaluation of socio-economic conditions and population trends.[1] Specific aims included determining population size, growth rates, geographic distribution, household characteristics, caste and ethnic composition, literacy and education levels, economic activity, disability prevalence, and housing structures, thereby providing disaggregated statistics by sex, age, place of birth, mother tongue, religion, and other variables for evidence-based development strategies.[1][9]Methodology
Enumeration Approach
The 2011 National Population and Housing Census of Nepal utilized a modified de jure enumeration approach, counting individuals at their usual place of residence—defined as the location where they had lived for six months or longer in the preceding 12 months—while making exceptions for homeless persons, nomadic groups, and those temporarily absent, who were recorded where found on the census reference date of June 22, 2011.[1][9] This method, adopted consistently since the 1952/54 census, aimed to capture stable residency patterns amid Nepal's rural-urban migration and seasonal mobility, reducing volatility associated with pure de facto counting.[1][10] Enumeration proceeded via door-to-door visits conducted by approximately 31,000 trained enumerators, supervised by 7,900 field officers at a ratio of 1:4 to enhance oversight and data accuracy.[1] Prior to full enumeration, a household listing phase mapped and registered structures from May 15 to approximately May 29, 2011, delineating enumeration areas (EAs) prepared since 2009.[10] The core enumeration ran from June 17 to 27, 2011, covering all 75 districts and ensuring no Village Development Committees or wards were omitted, with independent civil society monitoring to verify completeness.[1][11] Data instruments included a short-form schedule applied universally for basic household and individual details (complete enumeration) and a long-form schedule for in-depth topics administered to every eighth household via systematic sampling, enabling efficient resource allocation while maintaining comprehensive coverage.[9] Enumerators, recruited locally and trained for 10 days on procedures, concepts, and questionnaires, filled forms by interviewing household heads or knowledgeable adults, with responses coded via circling options to minimize errors.[1] Quality controls during fieldwork encompassed spot checks, re-interviews, and supervisory reviews, yielding a net under-enumeration rate of 4.0%.[1]Data Topics and Instruments
The 2011 Nepal National Population and Housing Census employed three primary data collection instruments: a Household Listing Form, Schedule 1 (short form), and Schedule 2 (long form). The Household Listing Form was used in the initial phase to enumerate and map all households within enumeration areas, capturing basic details such as the number of houses and households per structure.[12] Schedule 1 facilitated complete enumeration across the entire population, while Schedule 2 targeted a stratified sample of approximately 12.5% of households (using an 8:1 sampling ratio) for expanded inquiries.[13] These instruments were paper-based, administered by trained enumerators during door-to-door visits from November 11 to 25, 2011, with provisions for institutional populations and remote areas.[1] Schedule 1 focused on core household and individual attributes essential for benchmark population counts. Household-level topics included housing type (e.g., structure materials for walls, roof, and floor), ownership (distinguishing female-headed or female-owned properties for the first time), access to facilities (e.g., water source, sanitation, electricity, cooking fuel), and assets (e.g., radio, television, livestock holdings). Individual-level data encompassed name, relationship to household head, sex, age (in completed years), caste/ethnicity, mother tongue, second language, religion, marital status (categorizing never married, first monogamous marriage, polygamous marriage, or remarriage), literacy (in any language), and current school attendance for those aged 5 and above.[11] [14] These topics enabled derivation of basic demographic profiles and housing conditions for the full enumerated population of 26,494,504 persons across 6,743,952 households.[1] Schedule 2 extended inquiries for sampled households to capture socioeconomic depth. Household topics overlapped with Schedule 1 but added details on agricultural land ownership and production. Individual topics included detailed education (highest level completed and major field of study for those aged 5+), economic activity (occupation, industry, status in employment, months worked in past year, including non-economic household tasks), migration (place of birth, years of residence in current district, reason for migration, and place of residence five years prior), and disability (type and severity for those reporting any impairment).[14] [13] New inclusions addressed demands for granularity, such as sub-caste (thar) identification within ethnic groups and explicit female property rights, reflecting policy priorities for equity analysis without altering core de jure residency definitions.[15] This dual-form approach balanced comprehensive coverage with resource constraints, yielding data on fertility, mortality proxies, and labor force participation from the sample.[1]Execution
Field Operations
The field operations of the 2011 Nepal National Population and Housing Census were conducted in two primary phases: household listing and individual enumeration. Household listing, carried out primarily by supervisors, occurred from May 15 to June 1, 2011, to identify and map households within enumeration areas, which were typically wards or parts thereof, allocated based on estimated workload.[1] [16] Individual enumeration followed from June 17 to June 27, 2011, with June 22 designated as the census reference date (sunrise), during which enumerators collected demographic, social, and housing data using paper-based questionnaires.[1] [16] A workforce of approximately 52,000 to 56,000 enumerators and 7,500 to 12,000 supervisors was mobilized, organized hierarchically under district census offices, area census offices, and supervision areas, with a supervisor-to-enumerator ratio of 1:4 to enhance oversight.[1] Recruitment drew heavily from local teachers and community members, emphasizing inclusivity with over 40% of staff comprising women, Janajatis, and Dalits.[1] Training lasted 5 to 10 days for both enumerators and supervisors, conducted in May and early June 2011 by Central Bureau of Statistics officials, covering questionnaire use, mapping, and data collection protocols.[1] Logistical efforts included printing 15 million questionnaires, 60,000 enumerator manuals, and 15,000 supervisor manuals, distributed via road transport to 67 districts, air-drops to remote areas like Bajhang and Humla, and postal or local administrative channels where necessary.[1] Supervisors performed spot checks on 10% of households, re-interviews, and field verifications, supplemented by independent monitoring from civil society organizations across all 75 districts.[1] Operations faced logistical hurdles in Nepal's mountainous terrain, including weather disruptions, floods isolating areas, and transportation delays in remote regions, alongside incomplete household lists and occasional respondent reluctance.[1] Political transitions and security concerns in certain wards necessitated adaptive measures, such as extended timelines in affected zones, yet the de facto enumeration approach ensured coverage of residents present on census day.[1] A subsequent post-enumeration survey in September 2011 estimated a net under-enumeration rate of 4.0%, informing data adjustments.[1]Challenges Encountered
The 2011 Nepal census faced significant logistical hurdles due to the country's diverse and challenging topography, including high-altitude Himalayan regions, rugged hills, and remote Terai plains, which complicated enumerator access to isolated settlements requiring extensive trekking and limited transportation options.[15] In particular, conflict-affected areas in the Terai and remote hill districts proved difficult or impossible to reach fully, exacerbating undercoverage risks in these zones.[15] Field operations were further strained by inadequate training of enumerators, many of whom were school teachers with limited preparation for census-specific tasks, leading to inconsistencies in data recording and potential quality lapses.[17] Language barriers compounded these issues, as local linguistic groups were often not mobilized, resulting in communication gaps between enumerators and respondents in linguistically diverse communities.[15] Ongoing political instability from Nepal's post-civil war transition, including stalled peace processes and weak governance, created security concerns in certain regions, hindering timely enumeration and contributing to incomplete coverage.[18] Management of human resources, logistics, and finances also demanded careful oversight to mitigate delays in material distribution and enumerator deployment across Nepal's 75 districts.[19] These factors collectively challenged the Central Bureau of Statistics' efforts to maintain data integrity during the November 22–25 enumeration period.[20]Key Results
Total Population and Growth
The National Population and Housing Census 2011 enumerated a total population of 26,494,504 residents in Nepal, comprising 12,849,041 males and 13,645,463 females.[1] This figure represented households across all 75 districts and 3,915 local units, with de jure enumeration principles applied to capture usual residents.[1] The census, conducted primarily from November 11 to 25, 2011 (corresponding to Mangsir 1-15 in the Nepali calendar, with a reference night of November 10), provided the baseline for demographic planning amid Nepal's post-conflict stabilization.[7] Compared to the 2001 census total of 23,151,423, the 2011 count indicated an intercensal increase of 3,343,081 persons, or a total growth of 14.45 percent over the decade.[7] The average annual exponential growth rate decelerated to 1.35 percent, down from 2.25 percent in the 1991-2001 period, reflecting factors such as improved access to family planning, out-migration for employment, and residual effects from the Maoist insurgency (1996-2006) that disrupted earlier trends.[7] This slowdown aligned with broader South Asian patterns of declining fertility rates, though Nepal's rate remained above replacement level at approximately 2.4 children per woman during the period. Rural areas accounted for the majority of the population at 79.8 percent, but urban growth outpaced rural at 2.69 percent annually, driven by internal migration to emerging urban centers.[7]Demographic Profiles
The 2011 Nepal census recorded a total population of 26,494,504, comprising 12,849,041 males and 13,645,463 females.[1] This resulted in a national sex ratio of 94.2 males per 100 females, reflecting a slight female majority, with urban areas showing a higher ratio of 104 males per 100 females compared to 92 in rural areas.[1] [21] Age structure data indicated a youthful population, with significant portions in dependency and working-age groups. The population aged 0-14 years totaled 9,248,246 persons (34.9% of the total), the working-age group of 15-64 years numbered 15,563,369 (58.7%), and those aged 65 and over were 1,682,589 (6.3%).[1] This distribution yielded an overall dependency ratio of approximately 70 dependents per 100 persons in the working-age population, calculated as the sum of child (0-14) and elderly (65+) dependents relative to the 15-64 cohort.[1]| Age Group | Population | Percentage |
|---|---|---|
| 0-14 years | 9,248,246 | 34.9% |
| 15-64 years | 15,563,369 | 58.7% |
| 65+ years | 1,682,589 | 6.3% |
Ethnic, Caste, and Linguistic Composition
The 2011 Nepal census enumerated the population across 125 distinct caste and ethnic groups, encompassing a diverse array of indigenous nationalities (Janajati), hill-origin castes, Terai-origin castes, Dalit communities, and religious minorities such as Muslims. This classification relied on self-reported identification, capturing groups from Tibeto-Burman, Indo-Aryan, and other linguistic-cultural stocks, with significant regional concentrations: for instance, hill castes predominant in mountainous and mid-hill regions, while Terai groups like Tharu and Yadav cluster in the southern plains. The total enumerated population stood at 26,494,504, with no single group exceeding 17% dominance, underscoring Nepal's fragmented ethnic mosaic rather than a monolithic national identity.[1]| Rank | Group | Population | Percentage |
