The greatest difference between males and females is typically observed in the age group of adolescents, particularly during the transition from early to late teenage years. During this period, variations in physical development, social behavior, and psychological factors can lead to significant differences in interests and activities between genders. These disparities often become more pronounced around ages 13 to 17, reflecting changes in identity, peer influence, and societal expectations.

What is the difference between statistical age standardisation and age-gender standardisation?
Whereas age-standardization adjusts for underlying differences in the age distribution of the combined male-female population, age/sex-standardized rates adjust for differences in the population distribution by both age and sex simultaneously.Age/sex-standardized rates are NOT the same as sex-specific age-adjusted rates.Like age, sex has a powerful influence on disease rates. Males and females have markedly different incidence, prevalence, and mortality rates for certain diseases and males have a shorter life expectancy than females.Therefore, in order to fully account for these differences, researchers may want to adjust for both age and sex when making comparisons for some conditions.The calculation for age/sex adjustment differs from age-standardization in that the individual age-specific rates are stratified by sex and are applied to the standard population stratified by sex.The requirements for the calculation of age/sex standardized rates are:Study population by age and sexStandard population by age and sexNumber of events for males and females in the study populationFormulaei(f) is the number of events for females in age group iei(m) is the number of events for males in age group ipi(f) is the number of females in age group i the study populationpi(m) is the number of males in age group i the study populationPi(f) is the number of females in age group i in the Standard populationPi(m) is the number of males in age group i in the Standard populationFor each age stratum the expected number of events is the sum of the expected number of events for males plus the expected number of events for females in that stratumAge-specific expected events= Ei=[(ei(m) /pi(m) ) *Pi(m) ] + [ (ei(f) /pi(f) ) *Pi(f) ]The age/sex Standardized Rate (per 100 000) is the sum of all expected events divided by the total standard population= [ Sum(Ei)/Sum(Pi)] * 1000
What age group shows the greatest difference between males and females?
The teenage years typically show the greatest difference between males and females in terms of physical and psychological development. This can be attributed to the hormonal changes and growth spurts that occur during this period, leading to noticeable disparities between males and females in areas such as height, muscle mass, and emotional maturity.
