The median age for u. s. blacks currently is 30.9 years; for u. s. whites it is 42.3 years. (a) based upon this information, give two reasons why the black median age could be lower than the white median age. (select all that apply.)

There are quite a few reasons that this difference could be observed. The lower black median age could be connected to the greater number of births in the black minority group than in the whites. Another reason could be the aging of the non-Hispanic white group to a post child-bearing age and consequently the general aging of this subgroup of the population. In general, differences in group medians are due to the distribution of ages and the observed range of the ages in the two dissimilar population groups.
