Abstract

Our previous studies indicated that temperature and photoperiod were not involved as temporal variables in effecting the annual changes in human conceptions in the USA. However, temperature still receives attention in the current literature as the important variable in determining the temporal pattern of conceptions. Therefore, we present here a replication of our previous study, involving two additional 11‐year cycles of birth data in the USA, from the interval 1945 thru 1966. The data are transformed to remove linear trends, to remove over‐all mean differences, and to remove differences in amplitude. The data are then clustered into the regional groups determined by the previous study. The replication was obtained when these groups exhibited similar patterns within a 11‐year period and among 11‐year periods. The data from four 11‐year intervals are presented, representing more than 100 million Caucasian births in the USA from 1945 thru 1988. The subtle changes with time are described, and a comparison with a southern hemisphere pattern indicates, along with the other data, that temperature is irrelevant in effecting the annual pattern of changes in conceptions.
