Comparing ratios between groups using population estimates with confidence intervals

#1
Based on two national population surveys, I have estimates of rates of event A and event B (with 95% confidence intervals) by age category and gender. The widths of the confidence intervals are not the same between age-gender groups.

How can I check if the ratio A/B is elevated in any age-gender groups?

For example, say A is hospitalizations for bicycle riding and B is past year bicycle riding.

Are the respondents linked between the two surveys? Or are they just two different random groups of individuals?

There are two separate surveys, one for event A and the other for event B. Both surveys are representative for the same population.
