Given the information regarding incidence rates in both cities above, determine through direct standardization which city truly has the higher incidence rate of heart attack after age adjustment.

Age specific incidence rate
Young
West city. - among 5000 people 100 are having heart attack. So incidence rate is 2%
East city. - among 2000 people, 20 have heart attack. So incidence rate is 1%
Old
West city. - among 1000 people, 100 have heart attack. So incidence rate is 10%
East city. - among 8000 people, 800 have heart attack. So incidence rate is 10%
Age adjusted incidence rate. -
West city
East city
32. According to the given scenario, west city shows more incidence of heart attack. In case of younger adults, it was 2%in west city whereas it Is1% in east city.
