Nigeria 1000m. Contraceptive Use
Nigeria 1km Contraceptive Use

DATASET: version 1.0 estimates of the proportion of women aged 15-49 per grid square that were using modern contraceptive methods in 2013; the data series is comprised of two datasets, a) predicted proportion of female contraceptive use (NGA_contraception_F.tif), and b) related uncertainty map (NGA_contraception_interdecile.tif).

REGION: Africa

SPATIAL RESOLUTION: 0.00833333 decimal degrees (approx 1km at the equator)

PROJECTION: Geographic, WGS84

UNITS: Dataset a: Proportion of women aged 15-49 who were using modern contraceptive methods (median value); dataset b: Interdecile range - the difference between the first and the ninth deciles (uncertainty dataset).

MAPPING APPROACH: Bayesian geostatistical modelling methods in combination with high resolution gridded spatial covariates applied to GPS-located household survey data on contraceptive use, from the DHS program, circa 2013.

FORMAT: Geotiff (zipped using 7-zip (open access tool): www.7-zip.org)

FILENAMES: Example - NGA_contraception_F.tif = Nigeria (NGA) female (F) contraception estimates.
