Thank you for your help! May I bother you once again to tell me the specific reference material (article) on which you read this information (if you remember it/can get it easily)?.
Sorry, may I ask about the reference of age categories? for the standard classification that mentioned by @omotola Olasupo is old reference (1982). is there the update one?
The one which i referred from the above mentioned reference: who is mainly for girls and women. i hope i could find the universal age group definition and its cut off points. thanks
Hi. I need help. I am writing a paper on nursing students perception about their clinical learning environment in my country- The Gambia. I am having trouble with caterigorizing the ages of my students which ranges from18 - 50. Any suggestions?
I will recommend you look at the age categorisation structure adopted the Demographic and Health Surveys. The are a standardised and provides accurate measurements for health research.
