The document outlines several common characteristics of developing countries according to development economist Michael Todora, including: low standards of living, low productivity, high population growth and dependency burdens, high unemployment and underemployment, dependence on agriculture and exports, imperfect markets and limited information, and dominance in international relations. However, it also notes significant diversity among developing countries in factors like resources, history, demographics, industry structure, and politics. While developing countries share some characteristics, there are also substantial differences, so generalizations should be avoided.
