In a sample of 282 marriages in New Nubia in Egypt, 39% were between first cousins and 21% between less closely related kin. The average number of liveborn offspring in first-cousin marriages was higher than in marriages between more distant relations and unrelated spouses, but the number of deaths among children of first-cousin couples was also higher.

From part of a survey conducted in five European countries, Belgium, France, Great Britain, Italy and West Germany, data are given on the opinions of 4207 fertile married women and their husbands on ideal family size and on whether their existing children were planned or not. Data are tabulated according to the respondents' ages and the number of children in their existing families. Differences and similarities between various countries are discussed.

One hundred and fifty-two randomly selected pregnant women were examined and followed up by interviews and psychological tests during pregnancy and after parturition. The present paper is focused upon factors which determine the woman's preference for the sex of her expected child. It was shown that women who already have one or more children generally wanted the expected child to be of the opposite sex to her youngest child. Thus, the main part of the study was limited to eighty-one nulliparous women.

Associations were found between the woman's preference for the sex of the child and several factors such as the sex of her own siblings and her position among them, her education, intelligence and degree of field-dependence indicating immaturity and lack of autonomy.

Several of the findings presented refute the common supposition that nulliparous women generally want to give birth to a son, and that the arrival of a son is more satisfactory. Women wishing for a son were found to be somewhat more field-dependent than other women and somewhat more often reported that they had experienced a range of mental symptoms before the current pregnancy. Women wishing for a boy also reported more mental symptoms during the post-partum period. Moreover, those women who gave birth to a son reperted more symptoms at this time than those who gave birth to a daughter, and paradoxically the most affected were those who had wished for a son and had had their wishes fulfilled. The arrival of a daughter therefore seems to be equally satisfactory to the mother, at least as measured by the criteria used in this investigation.

The findings relating to marriage and fertility of the National Survey of 1960 Graduates show that highly-educated people are on the whole no exception to the generally observed principle of social and educational endogamy. Those from working-class homes, however, marry overwhelmingly into the middle class, so that marriage here constitutes a means of consolidating newly-won status. Respondents on the whole tended to delay marriage and family building while still engaged in full-time study, but more graduates are ultimately marrying and are doing so at younger ages than ever before. There are also certain consistent differences between the sexes, which indicate that women graduates are much more susceptible than men to the delaying influences on marriage and family building of the continued exposure to higher education.

A study has been made of the effect of a vigorous family planning campaign on one particular aspect of family limitation, namely female sterilization. The increase in numbers seeking operation suggests that, over the country as a whole, the method is not being employed as often as it could be, though it is emphasized that operation, as well as other methods of contraception, are not likely to make impact on the population problem unless there is a defined national policy.

In a sample of 165 FPA patients, 67% had stopped attending the clinic after 3 years. Half the loss could be accounted for by transfers, moves and ceasing to need contraception. The drop-out rate was not related to age, social class or number of children. Of the three methods generally pre scribed, the greatest attrition occurred amongst the cap patients. In a sample of twenty-seven LA patients, 48% had dropped out.

In all societies for which data exist, there is seasonality in the incidence of births, a major cause of which in the UK appears to be season ality in sexual activity.

In contrast to the findings of Cowgill for earlier periods in other places, there has recently been in Great Britain a greater degree of seasonality in legitimate than in illegitimate births and in upper-class than in lower-class births.

Part of the explanation of the change in illegitimate seasonality could be the recent increase in the numbers of illegitimate births. The greater seasonality of upper-class births could be due to longer and more mobile holidays.

The rural parish of Turcifal in Portuguese Estremadura in 1671 reflected its standard of living in an unexpected fashion. If the prices of grain grown by the people of this parish are used as an economic guide with high prices reflecting poor agricultural years and low ones representing successful harvests, and such data are then compared with the local statistics, interesting demographic facts result. The mean annual number of marriages and births did not differ significantly between good and bad harvest years. There were, however, a statistically significantly larger number of girls born in poor harvest years; whereas in good years boys were born in excess of the expected sex-ratio. It is suggested that poor nutrition during pregnancy, or possibly some other factor influencing both simultaneously, increased the incidence of unsuccessful gestations, which are more likely to be of males, resulting in a proportionately higher number of female live births.

Linear correlations between the price of wheat or barley and the mortality of females showed high significance when the grain is barley and a low significance when it is wheat, suggesting that there may have been a differential use of the food supply. No significance appears when the price of grain is compared with male mortality implying that the men had preferential access to scarce food. The sex-ratio at death, including all ages and all causes, shows an excess of females.
