Recent changes in world fertility

The quality and variety of fertility statistics have improved markedly in the world as a whole since the end of the Second World War, and in many of the countries where the statistical data had previously been unreliable, completeness of registration has been gradually achieved, whereas in others, some data have become available for the first time. In other countries there are, as yet, no reliable statistics from which to determine levels of fertility. Thus, the situation as regards amount and types of statistics needed to measure levels and trends of fertility throughout the world is still far from satisfactory and new and concerted efforts to fill the gaps in statistical information are sorely needed. Results of sample surveys and data obtained from various records can be used to fill the gaps in information, but such data cannot substitute for statistics collected in complete vital statistics registration systems and regular censuses of population. At present, only a minority, roughly one third of the world's population, is covered by adequate demographic statistics, and these inhabitants live for the most part in developed countries.
