Inuit Natality Rhythms in the Central Canadian Arctic

Abstract

SummarySeasonal variation in human natality is examined over a period of several decades for an isolated Inuit settlement in the central Canadian Arctic. The results substantiate earlier reports of the existence of a birth season in the first half of the year. The 2-decade period coinciding with the gradual concentration of the regional population into the settlement experienced a temporary disruption of this traditional rhythmic pattern. Family planning has been introduced in the modern period, yet birth seasonality is even more pronounced than during previous decades. Both planned and unplanned births occur predominantly in the first half of the year, indicating the paramount importance of behavioural and social responses to extreme seasonal variation.
