... pc01_td_app_p_road, pc01_td_school_primary, pc01_td_school_sec_above, pc01_td_college_tot, pc01_area (and pc01_pca*)
pc01 VD variables converted and filled in between 01VD/01TD: pc01_td_railway, pc01_td_app_k_road, ...
villages merged into towns have been marked with pc11_town_pc01_village
location ids and names match PC01-PC11 PCA exactly
PCA population is nearly unaminously larger than TD population for 2001 and 2011
all populations are urban populations except for village -> town obs where rural PCA population is used in main vars
pc*1_tot_p variables take matching PCA and TD populations or best matching and are missing when these are not equal
Statutory towns in 2001: 3818, census towns: 1360
Statutory towns in 2011: 4055, census towns: 3891
N total = 7,888, n11 = 7,680, n01 = 5,162. Collasped towns: DMC, NDMC, Greater Mumbai, Hyderabad
Total matched: 7,581 = 4,950 (01-11 town-town) + 2,631 (01-11 vill-town)
NOTE! this ndvi dataset is unique on polygon_id - which is also unique on state/dist/subdist/village!
5-digit sub-class industries also available in ~/iec/misc_data/industries/nic/NIC-2004_detail_19jan2009.txt
The key is unique on BPL 2002 identifiers and multiple BPL 2002 villages can map to a single PC 01 village
dataset unique on bpl_district_id & bpl_state_id
2 extra towns that are split over districts in PCA and collapsed down in TD (Devaprayag, UK & Greater Mumbai, Delhi)
both entries in both districts for Devaprayag & Greater Mumbai saved in this key
key is for correspondence between PCA + TD and therefore matches count of smaller TD instead of larger PCA
location ids and names match PC01 PCA exactly
pc11_vd_agr_comm1-comm3 are cleaned commodity strings used for standard crop
crop1-crop3 are MAIN standardized, spell-fixed commodity names
13 sub_categories total, 5 categories
*_raw_id merges to VD data variable pc11_vd_agr_comm*, to raw string key as raw_id
NOTE! this evi dataset is unique on polygon_id - which is also unique on state/dist/subdist/village!
spill_sample is a broader specification than the pmgsy mainsample var.
