Christie is of Scottish origin and means "christe" or "christian". It's a unisex name, often used for both boys and girls, but it's more commonly seen as a female name. The name Christie gained popularity in the English-speaking world during the mid-20th century and has been steadily used since then. Some notable people with this name include American actress Christie Brinkley and British singer-songwriter Chrisie Hynde. In literature, Christie is also associated with renowned mystery writer Agatha Christie, though it's not confirmed if she was named after the Scottish origin of her name or simply due to a coincidence.
The name Christie experienced significant fluctuations in popularity over the course of a century, with peak years occurring during World War I and II. Between 1913 and 1920, the number of annual births named Christie more than doubled from 8 to 22, likely influenced by the famous English nurse and heroine, Edith Cavell, whose middle name was Christie. However, this popularity did not sustain beyond the war years, as the number of annual births with the name Christie subsequently declined and varied throughout the mid-20th century until the early 1970s when it began to rise again, peaking at 14 births in 1975. After that point, the popularity of the name Christie seemed to decline once more, with fewer than 10 births per year recorded after 1983. Overall, over the span of these statistics (1893-1993), there were a total of 884 births with the name Christie.
