Self-rated general health

Age differences

Mean scores were fairly similar across different age groups in 2006/07.

The highest mean score was found in the 35-44 age group (76.5), and the lowest among those aged 75+ (67.5).

Among young people aged 15 to 24, young women rated their general health as worse than young men (72.4 for young women compared with 76.9 for young men).  This pattern was reversed among older people, with men aged 35 and over reporting lower levels of general health than women.

Women’s mean general health scores were highest in the middle two age groups (35 to 54 years), whereas for males, they were highest among young men aged 15 to 24 and declined with age.
