Eliminating variables that are not known during pregnancy and others that are fishy for various reasons, here's the best model I could find:

Now let's build a model to predict the respondent's parity (number of babies born alive). I used a nonlinear model of age. The age3 term is probably overkill, but I thought I would show that it might not be a crazy choice. It doesn't have much effect on the predictions.
In [8]:
join.numbabes.replace([97], np.nan, inplace=True)
join['age2'] = join.age_r**2
join['age3'] = join.age_r**3
In [9]:

Now we can predict the number of children for a woman who is 35 years old, black, and a college graduate whose annual household income exceeds $75,000

And here is the prediction for a woman who is 25 years old, white, and a high school graduate whose annual household income is about $45,000.
In [12]:

So this person has a 75% chance of being currently married, a 13% chance of being "not married but living with opposite sex partner", etc.
