Information from: “The Bu language of Central Nigeria and its affinities ” . Roger Blench (2011)
20 percent certain, based on the evidence available
"The Bu regard their language and culture as distinct from the Ningkada [Jidda], but the differences between the two would appear to be very slight. There are perhaps 4000 speakers of Bu and about 2000 or less speakers of Ningkada (the Ningkada hamlets are extremely small). In both locations, immediate evidence suggests that both language and culture are very strong and are not immediately threatened."

LANGUAGE CONTEXT COMMENTS
"The Bu regard their language and culture as distinct from the Ningkada [Jidda] and they are now geographically separated, but the differences between the two would appear to be slight. A complete wordlist of Ningkada was not taken but some twenty words elicited in a rapid visit suggested that the two languages are the same, with some minor lexical and phonological differences."
"The villages of the Bu people are reached from Gbodu village, 18 km east of Akwanga on the road to Wamba. A road leading northwest from Gbodu reaches Nakere after 6 km. and then Rago, Maiganga and Abu. The villages of the Ningkada [=Jidda] are reached by a turnoff some 7 km. north of the Wamba junction. The road turns east at Kango and Jidda (the main settlement) is some 6 km. away. Two hamlets, Ningkada and Lago, are southwest of Jidda respectively 1 and 3 km. away. A further settlement on the main road, Wanga, is some 5 km. north of Kango."
