How UPPSC frames this topic
This topic sits in Mains General Studies-I on the syllabus line that covers women, population and associated issues, poverty and development, and urbanisation. Prelims asks for definitions and for how the Census is conducted. Mains asks you to discuss causes, effects and remedies, so tie each population issue to a development outcome and to the Uttar Pradesh context.
Where does official population data come from?
The Census is the official count of the population. In India it is conducted by the Office of the Registrar General and Census Commissioner, India, which works under the Ministry of Home Affairs, Government of India. Its website offers census tables for 2011, 2001 and 1991 in Excel format, a population finder for villages, sub-districts and districts, and district census handbooks.
| Data product | What it offers |
|---|---|
| Census tables | Tables for 2011, 2001 and 1991 |
| Population finder | Data for a village, sub-district or district |
| District census handbooks | Handbooks for the 2001 and 2011 Censuses |
| Sample Registration System | Reports on births and deaths |
| Population projections | Report covering 2011 to 2036 |
How is Census 2027 being conducted?
Census 2027 is being conducted in two phases. The first phase is house listing, held from 1 April 2026 to 30 September 2026. The second phase is the population enumeration. Census 2027 is digital: field staff carry a mobile app and record the information directly.
| Stage | Period for non-snow areas of Uttar Pradesh |
|---|---|
| Self-enumeration | 16 November 2026 to 30 November 2026 |
| House-to-house enumeration | 1 December 2026 to 4 January 2027 |
| Revisional round | 5 January 2027 to 9 January 2027 |

Which population concepts and issues should you know?
| Concept | Meaning |
|---|---|
| Population growth | Change in the number of people over time |
| Density | People per square kilometre |
| Urbanisation | Rising share of people living in towns |
| Dependency | Children and elderly relative to workers |
Rapid growth strains food, housing, health and education services. Urbanisation brings jobs but also pressure on water, transport and sanitation. Population issues are closely linked to poverty, the role of women and women's organisations, and the other topics on the same syllabus line.
A useful way to write a Mains answer is to move from data to cause to remedy. Start with what the Census records, explain why numbers differ across regions, and then suggest measures such as better health services, education for girls, skill training and planned town development. Remedies work best when they address several issues together instead of treating each one separately.
Answers also gain from showing both sides. A large and young population can raise the supply of workers and the size of the market. It can also raise unemployment and pressure on public services if jobs, schools and health care do not keep pace. Examiners reward answers that name the condition under which each outcome happens.
- Link population to poverty: large households with low incomes find it harder to escape poverty.
- Link population to women: education and health of women influence family size and child survival.
- Link population to urbanisation: migration towards towns drives city growth and slum pressure.
Uttar Pradesh angle
Uttar Pradesh is one of the States where the population enumeration of Census 2027 is being held earlier than the nationwide exercise, for its non-snow areas. Self-enumeration runs from 16 November 2026 to 30 November 2026, house-to-house enumeration from 1 December 2026 to 4 January 2027, and the revisional round from 5 January 2027 to 9 January 2027. This links to GS-V themes of governance and social issues. State population counts for earlier Censuses are available in the official census tables and are not reproduced here.
