A migration rate is not an annual movement count
MoSPI's Migration in India, 2020–21 estimated that 28.9% of people were migrants under its survey definition; the urban figure was 34.9%. The reference period was July 2020–June 2021, and the report was released on 14 June 2022. These percentages do not mean that those shares of the population moved during that single year. [1]
A migration stock describes people classified as migrants when observed. A flow describes moves, or people moving, within a specified interval. A flow series must say which of those units it counts, because one person can move several times. Confusing the two can turn decades of movement into an implausible annual growth story.
Birthplace and last residence tell different stories
Census D-01 classifies people by place of birth. D-05 examines last residence together with age, sex, reason for migration and duration of residence. They are complementary tables, rather than alternative labels for the same number. [2] [3]
Imagine someone born in Patna who lived in Delhi before moving to Pune. A birthplace table connects that person to Patna; a last-residence table connects the latest move to Delhi. If the person later returns to Patna, birthplace alone will not show the intervening moves. This hypothetical example explains why a question about origins can produce a different answer from a question about the previous destination.
Check what counts as residence
In the MoSPI survey, a migrant had a last usual place of residence different from the present place of enumeration at some time in the past. Its usual-residence rule uses a stay of at least six months, or an intention to stay for that long. A short visit and a move of usual residence therefore need not receive the same classification. [4]
The report also has a separate pandemic-era temporary-visitor measure. Do not combine that category with migrants without checking overlap and definitions. Similarly, a duration-of-residence group describes people still observed at the destination; it cannot recover every departure, return journey or repeated move that occurred during the interval. [4]
Choose the question before selecting the table
For employment research, examine migration reasons and work status. The official reason categories include marriage, education and other family circumstances as well as employment-related moves. The entire migrant population is therefore a poor substitute for a migrant-worker count. For language or housing research, origins, age and duration may be more relevant. [1]
Keep the geographic scale consistent. Moving between villages within a district, moving between states and moving internationally answer different questions. Record both the origin classification and the destination boundary. If a district has since been divided, preserve the historical geography or document a defensible boundary conversion.
Keep the survey's date and limitations visible
The 2020–21 evidence comes from additional PLFS questions during the pandemic. MoSPI cautions that the PLFS sample design was not specifically focused on migration. Use that evidence to understand patterns, while treating precise local estimates and present-day demand as separate research questions. [1]
On 2 February 2026, MoSPI announced a proposed Survey on Migration for July 2026–June 2027. An announced survey is not a published result. This guide, checked on 11 October 2026, does not turn that timetable into a new migration count. [5]
