There was an overall decline of 24% in the age-adjusted suicide rate from 1977 (13.7 per 100,000) to 2000 (10.4). The rate increased in most years from 2000 to 2015. The 2015 suicide rate (13.3) was 28% higher than in 2000. The rates for males and females followed the overall pattern; however, the rate for males was approximately 3-5 times higher than the rate for females throughout the study period.
从1977年（每10万人中有13.7人自杀）到2000年（每10万人中有10.4人自杀），经年龄调整后的自杀率总体下降了24%。从2000年到2015年的大多数年份里，自杀率都在上升。2015年的自杀率（每10万人中有13.3人自杀）比2000年高出28%。男性和女性的自杀率遵循总体模式；然而，在整个研究期间，男性的自杀率大约是女性的3至5倍。
