^aIn years 0 to 9 prior to survey; ^bDHS 2008 was selected instead of MIS 2010 because the 2008 sample was much larger; after verification with GPS coordinates, a non-city cluster of households was excluded; ^cdata in an earlier MIS survey (2006 to 2007) overlaps completely with the data in MIS 2010 as only data on children born in the last six years are included; ^dDHS 2010 was selected instead of DHS 2011 to 2012 as the 2010 sample was much larger; ^eafter verification with GPS data, several clusters of households located in Tema were excluded. DHS, demographic and health surveys; GPS, global positioning system; MIS, malaria indicator survey.
