A new website Ullbe.com claims to have the biggest database of universities in the world.

And true enough if you look at a small country like Denmark, then it lists not less than 146 universities (compared to Wikipedia which lists 8). Ullbe.com seems to include all small vocational educational facilities as well as musical schools. Although you can sort the search after popularity (defined how??) then the database gives a disorganised and chaotic impression.

However, it not so indiscriminate for other countries. In the United Kingdom it lists 200 universities compared to the 325 institutions recognised by the UCAS (Universities and Colleges Admission Service). In Panama it lists only 12, which also seems to be an underestimate considering all the small private universities in the capital alone.
