Lest anyone suspect that my standards for women are too high, let me allay those fears by enumerating in advance my three criteria for the match. First, the potential girlfriend must be approximately my age—let's say 21 plus or minus three or four years. Second, the girl must be beautiful (and I use that term all-encompassingly to refer to both inner and outer beauty). Third, she must also be reasonably intelligent—she doesn't have to be Mensa material, but the ability to carry on a witty, insightful argument would be nice. So there they are—three simple demands, which I'm sure everyone will agree are anything but unreasonable.
That said, I now present my demonstration of why the probability of finding a suitable candidate fulfilling the three above-noted requirements is so small as to be practically impossible—in other words, why I will never have a girlfriend. I shall endeavour to make this proof as rigorous as the available data permits. And I should note, too, that there will be no statistical trickery involved here; I have cited all my sources and provided all relevant calculations in case anyone wishes to conduct their own independent review. Let's now take a look at the figures.
Being neither a pedophile nor a geriatrophile, I would like to restrict my search for love to those whose age is approximately equal to my own. This is where things get a bit tricky, for two reasons: first, the census data is nearly eight years old, and second, the "population by age" tables in WP/01 are not separated into individual ages but are instead quantized into "15–19" (of whom there are 47472000) and "20–44" (population 258087600). Women aged 15 to 19 in 2001 will be aged 22 to 26 in 2008;

Now comes the real Gaussin Distribution.
…who are beautiful: 1785395
Personal attraction, both physically and personality-wise, is an important instigator of any relationship. Of course, beauty is a purely subjective trait whose interpretation may vary from person to person. Luckily it is not necessary for me to define beauty in this essay except to state that for any given beholder, it will probably be normally distributed amongst the population. Without going into the specifics of precisely which traits I admire, I will say that for a girl to be considered really beautiful to me, she should fall at least two standard deviations above the norm. From basic statistics theory, the area to the left of the normal curve at z = 2 is
and so it is this number with which we multiply our current population pool.
…and intelligent: 472106
Again, intelligence can mean different things to different people, yet I am once more relieved of making any explanation by noting that it, like most other characteristics, has a notionally normal distribution across the population. Let's assume that I will settle for someone a mere one standard deviation above the normal; in that case, a further
of the population must be discounted.
…and not already committed:141632
I could find no hard statistics on the number of above-noted girls who are already married, engaged, or otherwise committed to a significant other, but informal observation and anecdotal evidence leads me to believe that the proportion is somewhere around 50%. (Fellow unattached males will no doubt have also noticed a preponderance of girls legitimately offering, "Sorry, I already have a boyfriend" as an excuse not to go on a date.) For reasons of morality (and perhaps too self-preservation), I'm not about to start hitting on girls who have husbands and boyfriends. Accordingly, that portion of the female population must also be considered off-limits.
Discounting Lesbians and Bisexuals:128756
According to latest studies 8%(and increasingly increasing) of world population is homosexual and assuming 50% of those are female homosexuals. A rough figure counts to about 5% bisexuals among females. so discounting these 9%.
…and also might like me: 20421
Naturally, finding a suitable girl who I really like is no guarantee that she'll like me back. Assuming, as previously mentioned, that personal attractiveness is normally distributed, there is a mere 50% chance that any given female will consider me even marginally attractive. In practice, however, people are unlikely to consider pursuing a relationship with someone whose looks and personality just barely suffice. Let's make the rather conservative assumption, then, that a girl would go out with someone if and only if they were at least one standard deviation above her idea of average. In that case, referring to our previous calculation, only 15.8655% of females would consider someone with my physical characteristics and personality acceptable as a potential romantic partner.
It is here, at a pool of 20421 acceptable females, that we end our statistical analysis. At first glance, a datable population of 20421 may not seem like such a low number, but consider this: assuming I were to go on a blind date with a new girl about my age every week, Now this population of girls comprise of age group 22-44. Also simple law of exponential decay =(1/e) says that time constant of a LR or RC circuit is measured in terms of its charge /current decayed to 67% so let us assume that 33% area in 1/e grapgh is uselss for me.
I would have to date for 4191 weeks before I found one of the 20421 . That's very nearly 80 years.
