Rural populations are still the most numerous in tropical countries. But we can witness an unprecedent process of urbanization. However the dynamics of the phenomenon differs greatly in different countries and in different towns. As a matter of fact, the greatest overcrowded metropolis attract the greatest part of the migrants from rural areas; the attractive factors are multifarious and universal. This not easily controllable trend seems to be irreversible. The migrant farmers will generally find a job within the informed economic sector. The zones of spontaneous and precarious settlement are often their first environmental living conditions. Some of these unhealthy dwelling areas are subject to development plans; some of them being extremely well designed.
农村人口在热带国家中仍然占大多数。但我们可以看到一个前所未有的城市化进程。然而，这一现象在不同国家和不同城镇的动态变化差异很大。事实上，人口最拥挤的大城市吸引了农村地区大部分的移民；吸引因素多种多样且具有普遍性。这种不易控制的趋势似乎是不可逆转的。农民工通常会在已知的经济部门找到工作。自发形成的不稳定定居区往往是他们最初的居住环境。其中一些不健康的居住区域正在实施发展规划；有些规划设计得非常好。
