At subscription, all women done care about-given forms about their demographic analysis. This new article writers reviewed the newest ladies’ future maternity plan of the inquiring the brand new question, “Can you propose to features people/ any further people certain go out?” This new provided responses was in fact “Sure, I am able to”, “Zero, I will not”, and you may “I’m not sure”.
