Leif vs Per

Leif and Per compared on official birth-registration statistics and Namewise's recorded data. This page states what each name's record shows — it never picks a winner or scores one name against the other.

Higher on the chart is a stronger position. The scale is logarithmic, so the gap from #1 to #10 is drawn as large as the gap from #100 to #1,000.
