Distribution land/water for sub-satellite points for a given inclination

Hello all

A news item about the near uncontrolled re-entry of the Progress sparked a question. They said: 'Chances are very low it will come down in populated area'. Off course, Earth is mostly water. Any satellite will pass over land and water as it revolves around the Earth. Is there a table or approximation available how many of the sub-satellite points are on land or over water for a satellite with a given inclination?

A satellite with inclination 0 will pass over land in Central Africa, North-South-America, and islands near Sumatra and Borneo. It crosses the Pacific, Indian and Atlantic Oceans. All its sub-satellite points are mainly over water. A satellite with an inclintation of 10 will pass over other land and water areas. A Polar satellite will pass over all land and water -> 71% water and 29% land.

Anyone a table available?

Kind greetings
