Working Strategies Adopted
- There are 157 mouzas in our project area. The whole mouzas are divided into 40 clusters and one surveyor looks after one cluster.
- There are 8 field monitors and each field monitor (on an average) guide and supervise the activity of 5 surveyors.
- There are 3 data entry operators for data compilation etc.
- Each surveyor has prepared a cluster map and has a specific work plan. Surveyors submit their plan to the respective field monitor and field monitors submit their plan to the survey manager and survey manager to the field director.
- Every staff has a diary and it is being maintained daily. They write their daily achievements, problems and observations.
- Linkage building with panchayats, health sub centers, blocks, ICDS enters, SHGs etc. to have effective communication and interaction on the health and population issue.
157 Mouzas in Suri 1, Md Bazar, Sainthia & Rajnagar blocks of Birbhum district of W.B.
No of Households: 66343
No of SHDS Sampled Households: 13261
Selection Criteria for Blocks (filed site) of Birbhum District
Four blocks were selected purposively, taking into consideration:'
- Socio-Economic Status
- Urbanization Status
- Relative Proportions of Tribal and Caste Populations
- Availability of Infrastructure for the conduct of survey.
(A) From logistical and cost considerations, it was decided that a total of 12,000 households would be sampled from these 4 blocks for the formation of the cohort.
(B) We adopted the principle of probability proportional to size (i.e., total number of households) for allocation of the number of households to be selected from each block. Using this principle, the distribution of the number of households to be selected from each block is :
(C) Appropriate detailed data from Census of India, 2001, pertaining to these blocks are used. Appropriate portions of these data were used for allocating the numbers of households to be sampled from villages within these blocks.
(D) For logistical reasons, it was decided that sampling of households will be confined only to villages in which ≥ 200 households reside. The following table provides the distribution of the total number of villages and the number of villages of size ≥ 200 households.
(E) The number of households to be selected from each village of size is ≥ 200 house. A probability proportional to size (i.e., number of households in village) scheme was used for allocation of the numbers of households to be sampled from the villages.
(F) Sampling of households from within a village was done using a circular systematic sampling scheme.
