This ignores the period of the People’s Republic of Mozambique.

It’s possible that the expected figure should be higher, to reflect the 1979–88 period during which the position of Prime Minister was abolished.

This score is much lower than it really should be, because the erroneous inclusion of Ong Teng Cheong (who, as I understand it, should have been entered into Wikidata as Deputy Prime Minister instead) causes a disproportionately high error rate compared to the size of the dataset.

As with some other countries, there are several different Wikidata items representing the country over the relevant time frame, e.g. the Democratic Republic of the Sudan from 1968–85. However, Prime Minister position is currently modelled as spanning the whole period, so we’ll act as if it’s a single entity for scoring. We also include Omar al-Bashir as at least de facto Head of Government for his 30 year period.
