Gene Expression

Breeding the future

Some results from the GSS on what people perceive the ideal number of children is based on social variables. Additionally, the realized number of children the respondent has. I limited the sample to whites who were 40 or older (there are people who have children past 40, but I assume that most of the discrepancy, or not, between ideal and realized will be evident by that age).

    That’s great – thanks for this.

    Seems like almost nobody _wants_ to have zero children – tho’ about 25 percent of US women college grads end-up this way.

    Also seems that two is the ideal family size – which makes sense from the perspective of parental happiness but does not replace the population.
    Because nowadays (for smart and well organized people with access to fertility technologies) ‘ideal’ family size looks as if it means the the same as ‘maximum’ family size.

    I know you love data density, but those images are a bit too small.

    A visualization of statistics question: are the income graphs the right thing to display, or should they be smoothed (or bucketed) first?

    I’m sure that a smoothed version would be more pleasant, but would it make extracting information easier? and would it be worth the data thrown out?

    Interesting, thanks.
