People have always fallen in love.
There's nothing new about that, but what is new is the way they're meeting.
Our cover this week in The Economist is on modern love and the digital dating platforms that provide it.
In America today, about one third of marriages begin online and around the world there are 200 million people using dating platforms.
The biggest change is that online dating has massively expanded the pool of partners that a person can potentially meet.
Before, you might have been limited to the bar or your social group or your class, whereas now, you have tens of thousands of people to choose from online.
Online dating does have real problems though.
Before the age of the Internet dating was more of a social activity and you could always tell yourself that you were just having a drink in a bar with your friends.
Online dating takes that away and it's just you and the market.
Whatever your place in it is harshly apparent to you.
This can cause anxiety disorders and online dating has even been linked to depression.
According to messaging patterns analyzed on dating platforms Asian men are ranked as much less desirable than Asian women.
Black women are ranked as less desirable than black men by the same measure.
There are biases in terms of gender too.
Desirability of women starts high at 18 and then drops all the
way through their lives.
女性的魅力最大时是在 18 岁的时候然后随着年龄递减
In contrast, men start off less desirable and then their desirableness grows and grows until their 50 and then it trails off slowly.
相反地，男性的魅力一开始较低，然后开始提升持续提升到他们 50 岁，然后慢慢地减少
However, there is evidence that online dating is driving an increase in interracial marriages, at least in America.
You can, even if you don't tend to, meet people of other races to yourself.
Overall then, online dating seems to be a good thing.
It does have its problems, but it's helping people to bypass social barriers and to find better partners faster.
