The attempt to estimate per capita income for Egypt from 1886/1887 to 1937, presented in this paper, is part of an effort to evaluate British colonial economic policyduring the period of the British occupation of Egypt. For such an evaluation national income estimates covering the whole period would be very helpful. National income estimates worth the name, however, go back only to 1935–1939, and for years earlier than the 1950s they are of very poor quality. Compared with so many other lessdeveloped countries, Egypt has relatively rich statistics extending backward to the decades before World War I; but they do not really suffice for building up a national income series from either the production or the expenditure side, and from the income side there is hardly any information. In this situation, which both development economists and economic historians know only too well, the problem is how to make maximal use of existing production and expenditure indicators in order to come out with some idea of what per capita income developments may have looked like. Apart from gauging per capita income in Egypt during half a century before World War II, the paper serves more generally to illustrate a methodology that may find application for other countries.
