[Multiple births in the Netherlands, 1900-1993].
Data on multiple births in the Netherlands since 1900 are examined.  It is noted that "since 1975 the number of multiple births is increasing rather strongly, partly under the influence of the application of modern medical technology (e.g. hormone treatment) to infertility problems...."  Age distribution by sex among paternal and fraternal twins living in the Netherlands is also discussed. (SUMMARY IN ENG)
