A significant digital divide persists between men and women in many countries, and there are widespread digital divides between those with more or less income, associated with ICT affordability, with higher or lower educational attainment, particularly associated with the capabilities required for Internet use, and with other factors affecting the inclusion or marginalization of particular social groups, for example persons with disabilities. The capabilities of networks and devices have continued to grow extremely rapidly, doubling about every two years. The quality of ICT networks and devices, particularly in terms of bandwidth and speed of connectivity, has therefore also grown very rapidly, with broadband and even high-speed broadband networks becoming the norm in developed countries.
