A study finds that a Bayesian modeling framework, applied to the population of each 100-m grid cell in Nigeria, can estimate the population in each section with an overall error rate of 67 people per hectare in areas not covered by a microcensus survey; the results suggest that similar frameworks may be able to estimate population in resource-poor or conflict-affected areas where regular census surveys are not feasible.
