Hello DHS experts,
I'm puzzled by the variable ftype - urban / rural - in the 2018 and 2019 facility datasets for the Senegal continuous SPA. The percent of urban facilities increases dramatically from prior surveys, and all (2019) or nearly all (2018) all non-health huts are classified as urban in these two datasets, even in regions that previously had almost no urban facilities (Kedougou, Matam, Sediou). There's no indication that the sampling changed from 2017, and the other proportions seem consistent with prior years. The sampling description in the guides still indicates that health huts are sampled based on their attached health post, so it's quite odd that nearly all health huts are rural but the health posts are almost 100% urban. In addition, many of the facilities listed as urban in these surveys were classified as rural in 2016 and 2017 based on linking them using location or IDs from ANDS.
Was there a change in the definition of urban between 2017 and 2018 or might there be an error in this variable?
Thank you!
Hannah

Following is a response from DHS Lead Statistician, Ruilin Ren:
Thanks for your email and the question raised.
Regarding the urban-rural variable in SPA data, firstly, it is not a survey control variable because it does not exist in the health facility master list. Urban-rural is collected in the field based on the location of the facility and the urban-rural classification of the country.
Regarding the Senegal case specifically, firstly, Senegal's urban-rural classification was modified in 2017, this may affect the comparability of the urban-rural in later surveys.
Secondly, for the health huts, though they are attached to health posts in management, most of them are located in rural areas and remote areas. Their urban-rural definition can be different from that of the health post they are attached to.

Following is a response from DHS Research & Data Analysis Director, Tom Pullum:
Hi Hannah--Apparently we have nothing to add on this topic, and there's no alternative to checking with ANSD. We just know that there was a change in the sampling frame and a change in the definition of urban/rural around 2017. Hope you can find more documentation and I'm sorry that we don't have records on this. Best regards--Tom
