Distance distributions to different levels of care are shown for 3,692 rural Zambian births from the 2007 DHS. While most births were within walking distance of a facility offering delivery care (green), distances to facilities offering EmOC functions were larger. Few births were within walking distance to basic (red) or comprehensive (yellow) EmOC, most being 25 km or more from such care. BEmOC(−1), basic emergency obstetric care that may lack assisted vaginal delivery; BEmOC−2 and −4, facilities lacking two or four of the BEmOC signal functions, respectively; CEmOC(−1), comprehensive emergency obstetric care that may lack assisted vaginal delivery.
