P values in the rightmost column correspond to a χ2 test between age groups and responses to the survey questions.
Respondents divided by age groups do not add up to the corresponding total numbers in the left-most columns. This is due to age data missing for 55 respondents and recorded as > 74 years in 25 cases.
