Description

Data produced by the World Health Organization, UNICEF, LSHTM and Johns Hopkins University to estimate national low birthweight (LBW) and numbers for 195 countries. LBW data was collated through a systematic review of national routine/registration systems, nationally representative surveys, and other data sources, and subsequently modelled using restricted maximum likelihood estimation with country-level random effects. Data includes a list of 1447 rate data points used as an input to the modelled estimates, yearly national-level covariates for each of the 195 countries studied from 2000 to 2015, and information on estimated low birthweight rates from 2000 to 2015 for 148 countries with data. Stata code used to generate these estimates is provided.
