Marriage

1.

People can get married too young (some say early 20s is too young)

2.

Should you want to have kids, the woman ideally shouldn't be more than her mid-20s, since fertility generally dies down from then onwards - not saying she doesn't have a chance of conceiving later in life, but it becomes that much more difficult

3.

To put it crudely, there is the "dating market value" to be aware of and they vary between the sexes

4.

"Getting enough experience" isn't really a thing that suit women unfortunately; for men, it's somewhat important

5.

Should you have kids, the person you are going to have them with should be someone who will be a good parent and want kids to start off with. The person needs to be mature enough to handle having kids though.

6.

People need to figure out what they want before getting into marriage

7.

In some cultures, there are arranged marriages

8.

In some cultures, you are not "permitted" to date until you're in your late 20s

9.

Biologically speaking the person you are attracted to and can be in a relationship with, isn't determined by societal expectations, religion, race, etc. Anything of the sort is usually very superficial and often ruin potential relationships and marriages. Finding said person will take time, and unnecessary requirements can mean the sort of person you are looking for will take longer to find or doesn't exist.

10.

Financially speaking, you should get married when you are financially stable. In the current economic climate around the world, this is pushing marriage later and later in life.

11.

The ages some of our grandparents married were in their late teens and early 20s.

12.

A lot of modern marriages happen in the mid2-s to late 30s. This is relatively late compared to previous generations.

13.

Careers of either potential spouses can delay marriage, which can introduce complications as well as cause problems for family life.

14.

The cost of divorce can be significant, as well as psychologically detrimental. This cost rises a lot due to the current economic climate, which acts as a deterrent.

15.

Paternity fraud is also a thing which deters marriage, or at the very least imposes a longer due diligence period

16.

The current casual dating culture has more or less deterred marriages for both sexes, as well as desirability of each of the sexes

17.

Cultural attitudes to dating have more or less acted as a deterrent for certain partners, and securing someone who is of marriage material is that much more challenging.

18.

Should the persons concern come from a culture that endorses dowry or relatively significant financial payments (which many would find absolutely disgusting), the economic climate and cultural expectations have more or less inflated such requirements in recent times. Again acting as a deterrent as well as dissuading marriage altogether.

19.

Marriage is also influence by the preferences of the parents (they shouldn't be, but they are). Depending on the parents concerned, this can act as a further deterrent.

20.

Mental maturity has seemed to have delayed with the more recent generations. This can mean suitability for longer term partnerships can also be delayed.
