Fig. 4: Average-adjusted annual per capita LPG consumption.

Mean LPG consumption along with error bars that represent 95% CIs. Annual per capita consumption was obtained by dividing 12 months by the self-reported average duration (months) until a typical cylinder refill runs empty, multiplying that quantity by the LPG cylinder size and dividing by the number of household members. Per capita consumption is presented with covariates centred at their mean.
