    Comparing ratios between groups using population estimates with confidence intervals




    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.

    Re: Comparing ratios between groups using population estimates with confidence interv

    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.
