many kids born outside of marriage to women under 30

there is an article called For Women Under 30, Most Births Occur Outside Marriage that is about  women who have babies at a young age under the age of 30 written by jason deparle and sabrina tavernise its about single women  who have babies under the age of 30 that are not in a relationship. in the article it says more than half of births from american women under 30 occur outside marriage. most of those women are minorities black, or latin american. 
one lady was 27  in a on and off relationship  when she found out she was pregnant and her babies dad was a sears clerk and was not ready to get married and have a full term family so she is one of the people  that will be under 30 i think there is alot of people that are born outside of marriage i dont think it is a bad thing well why should it be all people do not want o get married so if they dont want to get married  yeah kids are going to be born outside of marriage and  and if people  want to have sex young that might lead to the birth of child and who you decide to have a baby with and when you want to have a baby is your  choice but i also think that it is nothing wrong with having sex while your not married or having a baby if your not marrried bacause some mother are independent enough to take care of there selves  and there kids or babies on there own
