Reading the Survey: Work in Three Nagaon Villages
In a field study, a class surveyed 600 households in three villages of Nagaon district, Assam. The villages differ: one lies on the highway, one is flood-prone, and one is 9 km from the highway. The main-worker data are shown below.
| Indicator | 2011 | 2023 |
|---|---|---|
| Main workers in agriculture | 64% | 41% |
| Main workers in construction | 9% | 22% |
| Main workers in transport and trade | 7% | 12% |
| Main workers in services | 20% | 25% |
| Women among main workers | 18% | 27% |
| Households with a seasonal migrant | 11% | 29% |
| Average days of employment per year | 214 | 168 |
The students also found that 78% of construction workers have no written contract, 62% of migrants go to Kerala and Tamil Nadu, the villages have one high school, and 41% of workers aged 15โ24 have completed class X. A newspaper report used the table to claim that the villages had 'moved into the service sector'.
1. Interpret the occupational change. Is it a shift to the tertiary sector or something else?

Not a simple shift to services. The largest absolute gain is in construction, which is secondary, not tertiary: 9% to 22% (+13 points). Services rose only 20% to 25% (+5). Agriculture fell 64% to 41% (โ23). So the correct description is distress diversification into informal construction, not a service-sector transition.
Evidence for distress: average employment days fell from 214 to 168; 78% of construction workers have no written contract; seasonal migration rose from 11% to 29%. People are not moving to higher-productivity jobs; they are filling the gaps left by shrinking agricultural work.
Gender: women's share of main workers rose from 18% to 27%, but this may reflect low-paid piece work rather than empowerment; the survey does not record wages, so we cannot tell.
Caution: 'main worker' is defined by more than six months' work, so a worker who does construction for four months and farm work for three may be misclassified.
2. Identify two limitations of the survey data and explain how you would correct them.

Limitations:
- Migration and absence bias: households with a seasonal migrant may be absent or under-reported. If 29% have a migrant, the survey may miss the most dynamic or most distressed households. Correct by listing absent members and interviewing them by phone.
- Recall and definition bias: respondents may report 'construction' for any casual manual work; 'main worker' hides multiple activities. Correct with a time-use diary for a subsample and an explicit question on secondary occupations.
- Small sample and village selection: 600 households in three villages cannot represent Nagaon district. Correct by stratifying villages by distance from the highway and by flood exposure.
Follow-up: a wage and contract module, plus a repeat survey after one agricultural year, would test whether construction is absorbing labour productively or merely parking it.
