Table฀1.1฀(based฀on฀United฀Nations฀2003฀figures)฀shows฀the฀estimated฀numbers and proportions฀of฀former฀immigrants฀with฀respect฀to฀five฀selected southern African฀ countries.฀The฀estimated฀international฀migrant฀stock in Namibia฀increased฀from฀ 42฀000฀(4.5%) in 1976฀to฀143฀000฀(7.5%) in 2003.฀The฀same฀applies฀to฀Botswana,฀ whose฀foreign-born฀population฀also฀grew฀consistently฀from฀13฀000฀(1.6%) in 1976฀ to฀52฀000฀(3.0%) in 2003.฀On฀the฀other฀hand, South Africa, ฀which฀accommodates฀ by฀far฀the฀largest฀estimated฀number฀of฀immigrants in the฀sub-region,฀has฀seen฀a฀ proportional฀decrease in these฀numbers฀from฀5.5฀per฀cent in 1986฀to฀a฀significantly฀ lower฀3.0฀per฀cent in 2003.฀ Whereas฀39฀per฀cent฀of Africa s฀total฀population฀lived in urban฀areas in 2003,฀by฀ 2030฀the฀continent’s฀urban฀areas฀are฀likely฀to฀accommodate฀the฀majority฀(54%)฀of฀ its฀people฀(United฀Nations฀2004).฀As฀far฀as฀internal฀population฀redistribution in the฀sub-region฀is฀concerned,฀Table฀1.2฀(also฀based฀on฀United฀Nations฀2003฀figures)฀ shows฀that฀the฀rural฀populations฀of฀Botswana,฀Lesotho and South Africa are฀ purported฀to฀be฀currently฀experiencing฀negative฀growth,฀while฀Botswana,฀Lesotho฀ and Swaziland฀experienced฀rapid฀urbanisation฀between฀1976 and 2003.฀Botswana฀ was฀particularly฀affected฀by฀urbanisation฀processes,฀with฀the฀level฀of฀urbanisation฀ increasing฀from฀13฀per฀cent in 1976฀to฀50฀per฀cent in 2003. 4 Free download from www.hsrcpress.ac.za 10฀฀ •฀ migration in south and southern africa Table฀1.1฀Selected southern African฀countries’฀immigrant฀populations฀฀ (international฀migrant฀stock) ฀ Botswana
