Relationship between urban living and the prevalence of childhood anaemia

Specific Objectives

• To analyze whether urban living described by raster data showing built up areas is correlated with disease prevalence.

• To determine if the urban/ rural designation given to geographic clusters in the Ghana Malaria Indicator Survey correlated with the built up areas raster data (presence of constructed buildings) from the WorldPopProject hosted by the University of Southampton and Global Human settlement data from the European Commission Repository.

Methods

The map was created using the tmap package (version 3.3) in R statistical software 4.0.3.

stars object downsampled to 1000 by 1000 cells. See tm_shape manual (argument raster.downsample)

Results

Accra and Kumasi, Ghana’s largest cities have a cluster of yellow circles (urban areas according to the  Ghana Malaria Indicator Survey) and black shaded areas showing that there are a lot built up areas that is constructed buildings from the 2014 Global Human settlement data.
