30-DAY Trailing Unemployment Rate

The 30-day trailing unemployment rate is computed at India and at the State level, and for urban India and for rural India. The survey design for estimation of 30-day trailing unemployment rate for India is based on the existence of 48 strata. The population is stratified at the State level and region-wise (rural and urban). Each of the 25 States sampled in our survey is further classified into Rural and Urban regions. Chandigarh comprises only of the Urban stratum. Thus, we have a total of 48 strata.
In computing the unemployment rate for the trailing 30-days, we consider all the households that were surveyed on the day and were accepted by an independent validations system on the same day. Both the conditions must be met for a household to be included in the estimation of 30-day trailing unemployment rate. Households that were surveyed on a day but are not accepted on the same day for any reason do not get included in the computation of 30-day trailing unemployment rate. If such households clear the validations on any other day in the same month, they are included in the estimation of monthly unemployment rate. Usually, 70 per cent of the households surveyed on a day do get validated on the same day.
The weight assigned to every member of the surveyed household, for trailing 30-days is calculated as a ratio of the estimated population (>= 15 years) on the day in the trailing 30 days to the surveyed population (>= 15 years) on the day in the trailing 30 days. For towns, it is the ratio of estimated population (>= 15 years) in the urban region of a State on the day in the trailing 30 days to surveyed population (>= 15 years) of the urban region of the State on the day in the trailing 30 days. And for villages, it is a ratio of estimated population (>= 15 years) in the rural region of a State on the day in the trailing 30 days to surveyed population (>= 15 years) of the rural region of the State on the day in the trailing 30 days.
Estimated population of members (>= 15 years) in urban region of a State in the trailing 30 days is calculated by using the Compounded Annual Growth Rate (CARG) on the Census 2001-Census 2011 data for the urban population of the State, compounded on a daily basis. Similarly, estimated population of members (>= 15 years) in rural region of a State in the trailing 30 days is calculated by using the Compounded Annual Growth Rate (CARG) on the Census 2001-Census 2011 data for the rural population of the State, compounded on a daily basis.
Surveyed population of members (>= 15 years) in urban region of a State on a day are members (>= 15 years) of all the urban households that were surveyed and accepted on the same day in the trailing 30 days. And sample members (>= 15 years) in rural region of a State on a day are members (>= 15 years) of all the rural households that were surveyed and accepted on the same day in the trailing 30 days.

The 30-day trailing unemployment rate for the jth stratum, is calculated using the following formula:

The Unemployment Rate for Trailing 30-Days:

The 30-day trailing estimations for India are calculated as a ratio of the total estimated unemployed persons in India to the total estimated labour force for the 30-day trailing period. The total estimated unemployed persons and labour force, is the summation of the estimated unemployed persons and labour force from each of the 47 strata, respectively.
