For what it’s worth, AMF has population data from distributing bednets to every household. As an organization that cares about being highly effective, AMF tries hard to get the number of nets right. The target is to have approximately one net per 1.8 people (a net covers two people usually, but then there are households with an odd number of people or with pregnant women).
It looks like AMF’s numbers are quite a bit higher, except in Bauchi state. This makes me slightly less willing to believe that Nigeria’s population numbers are inflated. But of course, AMF could have been a victim of bad initial population estimates, or could have had left-over nets that were then given to routine distribution or used in other locations. I don’t have any information about that.
Details vary by country. It’s often a process where enumerators go door-to-door and interview the head of household to determine how many people live in a household. There can be some incentives to over-report the number of people, to receive more bednets. However, there is a limit on the number of nets per household (usually 3 or 4), and some of the data is independently verified by a second team of enumerators.

AMF distributed nets in five Nigerian states in the last two years. You can see these distributions here: https://www.againstmalaria.com/Distributions.aspx?MapID=68
AMF reports the population for each state; to see them, click on the state name, then on “Pre-Distribution”. These numbers are:
I’ve compared the numbers with those from UNFPA, from here: https://data.humdata.org/dataset/cod-ps-nga

Thanks for this, do you know what process AMF uses to verify the number of people in a house? And if there are any incentives to under/over report.
There is some public information about this here: https://www.givewell.org/charities/amf#Registration
