As an American given name, it got a boost in popularity in 2012 after the rapper Kendrick Lamar (1987-) released his debut album.
This is a Modern Greek name as well. It has been conflated with the name Χρήστος (see Christos 2), which is spelled differently but pronounced identically in Modern Greek.
This was a popular name in the 20th century (especially the middle decades) in French, German, and English-speaking countries. In the United States Christina has been more common since 1973, though both forms are currently floundering on the charts.
