You look at the numbers and you think: “That’s impossible.” Uganda had about seven million people at independence in 1962, and in only 45 years it has grown to 30 million. By 2050, just over four more decades, there will be 130 million Ugandans, and it will be the twelfth biggest country in the world, with more people than Russia or Japan. Its population will have increased eighteen-fold in less than ninety years.
