The AIDS epidemic might be expected to have some import on marriage. Indeed, Gregson and colleagues emphasize that all demographic parameters are likely to change. Change in age at first marriage and proportions marrying should also affect fertility levels. Gray and colleagues (1997) found a pregnancy level among unmarried women of reproductive age of only half that found among married women. 10.7 per cent compared with 21.5 per cent. Mukiza - Gapere and Ntozi (1995) reported that first marriage rates were down in Uganda as increasing numbers of young women put off marriage because of fear of AIDS. It may be that they have greater control over the extra - union sexual activities of a boyfriend than of a husband, or it may be that some are now remaining virgin until marriage.
