See textbook p.131-133. Don't be fooled. In the latter case, the differences seemed huge when looking at the counts, but they were much smaller when looking at the percentages.
Counts can be very misleading.
Do not trust percentages unless their base is sufficiently large. As a rule of thumb, percentages should not be used when they are based on less than 50 cases. These rules apply to crosstabulations as well. Since there are 736 respondents over all, we would have less than 20 respondents per neighborhood on average. Clustered bar chart are functionally equivalent to stacked bar charts, i.e. you use them for the same purpose, they only differ in the visual appearance.
