Hausa in the United States

There's been some cleanup recently, but there are still some tracks left, starting in 2011.

There were also mentions in archived pages for India. The three categories for India, Pakistan and Bangladesh are here since extremely long. There were also (non working) attempts to do that for other languages in China. Multiple portals have tried to link them without coherence. In some cases these links were done in talk pages. This has long been a desire (with multiple evidences) to unify that, and multiple users on this wiki have thanked me for finding such solution (including several admins of this wiki, and the main admin that has checked every day what I did and thanked me once; I had several thanks from translators of several "minor" but official languages used in Central Europe or in South Asia, including in India which have difficulties to manage their many languages).

Sorting languages correctly is also important for this wiki to see how much they are distinguished, and it may also be used to justify the addition of their support. It can also help contributors to avoid confusing these languages and mixing translations. A minimal organization is needed when only the organization by mere language codes (not always very clear) often creates a confusion (not all users can understand the classification and names used in English, we've seen multiple errors in the past in various Wikimedia projects because of these confusions (and some of them are still not corrected years after they were signaled).
