It's odd how easily confused the names "Justin" and "Jason" are. It doesn't bother me anymore because I've just gotten so used to it that I'll respond to Jason if I know there are none around. Co-workers call me Jason. I got an email from someone in my class, addressed to Jason. Heck, my own grandmother used to call me Jason once in a while. While I like the name Justin a whole lot, it might just be easier on everyone if I change my name at some point. Curious whether other Justins suffer from this plight, I consulted www.justin.com. Turns out that it's quite common. My guess is that the problem will abate in the years to come. The Social Security Administration shows that Jasons are in decline. In its heyday during the '70s, Jason's popularity as a birthname was indeed strong. It ranked as the 3rd most common name given to boys; Justin was ranked 39th. However, Justin's popularity surged through the '80s. Cumulatively over the decade, Justin and Jason were ranked 12th and 11th respectively. Justin even made it into the top 10 for 1990. While neither Justin nor Jason have been in the top 15 names in the past 10 years, Justin has still been a much more common name for people born after 1990 than is Jason, for each of those years. I went and did lots of calculations based on 2000 census age distributions and concluded that currently, the Justin:Jason ratio = 0.568, assuming that migration of people named Justin and Jason are equal. It will be a couple more decades before they even out. But then all of this could be thrown off by the resurgence of either name in popularity like what happened in the past. Man, I am way too good at wasting my time...
