The tendency is not new, but, measured over fifty years, it is spectacular: more and more deliveries being programmed, births are rarer on Saturday and the Sundays. It is a short study in the rabrique Tendencies of  Population and Societies  *, the monthly newsletter of information of the national lnstitut of demographic studies (INED), that raises it by comparing the evolution of births according to the day of the week since 1950. One half a century ago, births split equitably in week, with the same a light surplus on Sundays (1 % more than daily average) as well as on Mondays (2 % in more). These surpluses are linked to sunday rest, deliveries having naturally tendency to start during rest, specify the authors.

For the same reason, the majority happened in the past at night. n am not there any more also, considering the m dicalisation of delivery. Today, about 30 % births are programmed, that it is a question of launching delivery (8%en 1972, 20%en 1998) or of envisaging a Caesarian section (3 % in 1972, 9 % in 1998). The doctors but also the future mothers choose then unjour of the week rather than the weekend. In comparison with 1950, he n it so 25 % of children in less the Sunday and bank holidays and 15 % in less the Saturday, or respectively
30 and 20 % of births in less than in the daytimes of the week. Also fewer births on Monday and the Wednesdays are noticed (day of lesser availability for the medical personnel or the mothers with children of school age).

However, if the fall of births the weekend was uninterrupted to in the eighties, she seems to have stopped since a dozen years. The proportion of programmed deliveries (30 %) could have attained a ceiling, in 30 %.
