Hi Shmitten Kitten!Whoa. Gulp. Wow. Exclamation point!
I'm a big fan of the blog. I've been living and dating in Philly for about nine years, so it's nice to hear about things from the other side. I recently read about a guy in London, Peter Backus, who used the Drake equation to figure out how many potential girlfriends there were for him in London. As an engineering grad student, my natural reaction was to replicate this for myself using Philly census numbers. I thought you might find it interesting. Feel free to skip the math and go right to my conclusions at the end. Here comes the science:
Potential girlfriends = (C_p * C_a * C_g * C_s) * (F_e * F_h * F_o * F_p)Plug all that in and round to an integer and it turns out that there are 10 potential girlfriends for me in all of Philadelphia. (Bonus nerd joke: if we use F_h = 0.125,F_o = 0.125 and F_p = 0.128, the answer is 42). Anyway, the point to all of this was to suggest that you should schedule some more speed dating sessions because it's rough out there and some of us need all the help we can get. Seriously, I did the math.
C_p = Population of Philadelphia = 1,448,394
C_a = Fraction of age appropriateness (25-34) = 0.148
C_g = Fraction of women = 0.535
C_s = Fraction that are single = 0.92
F_e = Fraction that are college grads = 0.2
F_h = Fraction that I find attractive = 0.07
F_o = Fraction that finds me attractive = 0.07
F_p = Fraction with a personality match = 0.1
C_a : The census reports this range and since I'm 33 it was a convenient number to use
C_g : Use 0.465 if looking for a b/f (sorry ladies). These numbers are for the entire population, likely closer to even for given age range
C_s : I couldn't find marriage numbers for age ranges so we'll go with 8% married/engaged for this age range
F_e : Since I've been in grad school forever, this seems like a reasonable criteria to set for me. The fraction of Philly with a college degree is 0.172 but it's likely higher for the given age range, so I went with 0.2. The number for a high school degree is 0.712
F_h & F_o : The original paper used 1/20 but here I'm using a number closer to 1/15, which is possibly overly optimistic.
F_p : 1/10 seems reasonable here

When we received this email from our reader, Jeff, we freaked out. His note is like if a TI-84 calculator and the VH-1 show Tough Love collided. There's A LOT of math involved, so all of you Mathletes out there, this one's for you:
