I think that Wikipedia is not correct here. There is the page "List of constituencies and suburbs of Windhoek" (Liste der Wahlkreise und Stadtteile Windhoeks / https://de.wikipedia.org/wiki/Liste_der_Wahlkreise_und_Stadtteile_Windhoeks), unfortunately only in german, which Chtrede created in 2018. Something comparable does not exist yet, to my knowledge (unless you could find something at the municipality of Windhoek).
