Comment from Lightsider
- Where does the information about the village nodes in SW Burkina Faso (e.g. node # 3841367490) come from?
- Are you sure they are villages (and not hamlets)
- What do you mean by the "capital" and "admin_level" keys? -
Comment from Verdy_p
All populations come from the 2012 general population survey, finalized and officialized for the municipal elections that toook place after that.
There's a complete PDF listing all communes/departments and their member "villages" (official term) or "secteurs" (only in capitals of departments/communes and a few other towns which had more than 10 000 inhabitants when they were officially subdivided, a few ones are still subdivided even if their population have decreased) with their finalized population: A "secteur" may belong to only one town or city (and also in a single arrondissement, in the two special cities of Bobo Dioulasso, and Ouagadougou).The electoral file is the most up to date source of population (as opposed to the older file published in 2012 by INSD which contained **preliminary** results, the electoral file is finalized and has been officialized).
For now there's not been any newer figures published.
capital=* indicate the minimum level at which a place is the capital of an admin boundary. This is documented.
admin_level=* is used to distinguish villages from departments/municipalities. Note that a "city" or town is not always an administrative unit and not at admin_level 8 by itself when it is subdivieded into "secteurs".
Look at http://wiki.openstreetmap.org/wiki/WikiProject_Burkina_Faso/subdivisions
and its separate subpage for municipalities (all of them are départements, they are also communes but there are 3 kinds of communes; and there's a single commune by department, with the same name, but whose territorial compentence is limited to only the urbanized areas with permanent residents, but does not cover the rural parts of the department with transitory populations, as this space is managed by the national state represented locally in the département):

Comment from Verdy_p
Final note: the list of communes is not fully dimilted by borders.
There are no open geographic data available at this time for their limits except descriptions: it is important to geolocate all villages listed in these documents in order to estimate boundaries (the list of villages allows recognizing some natural borders for departements, but note that these borders are still not the borders of municipalities that are smaller.
These borders however should be helpful to help geolocalize many things. But will still need to be imporved over time. Their precision is not decimetric like in Europe, but within about 500 meters in rural areas. We'll see later if a cadastre is implemented and published ut it will mostly concern first the urban areas of communes and for now the best open geographic sources are aerial imageries, where we can locate roads and rivers and most tracks, but not within forests (but there's not a lot of dense forest in Burkina, except in the East, and they are almost not cut by any administrative borders, most often defined along rivers).
