During the period between 1999 through 2017 , the age-adjusted suicide rate has increased 33% from 10.5 per 100,000 in 1999 to 14.0 in 2017 in USA. The average annual percentage increase in rates accelerated from approximately 1% per year from 1999 through 2006 to 2% per year from 2006 through 2017. Still males are leading the suicide chart,as gap of data between male and female is about 16.3 per 100,000 .These findings have been published by National Center for Health Statistics in recently released data analysis report of suicides in USA .
It is dangerous trend as fertility rate in USA is declining.We need to take significant remedial measures to control the situation.The age-adjusted rate of suicide among females increased from 4.0 per 100,000 in 1999 to 6.1 in 2017, while the rate for males increased from 17.8 to 22.4.

Summary
This report highlights trends in suicide rates from 1999 through 2017. During this period, the age-adjusted suicide rate increased 33% from 10.5 per 100,000 in 1999 to 14.0 in 2017. The average annual percentage increase in rates accelerated from approximately 1% per year from 1999 through 2006 to 2% per year from 2006 through 2017. The age-adjusted rate of suicide among females increased from 4.0 per 100,000 in 1999 to 6.1 in 2017, while the rate for males increased from 17.8 to 22.4. Compared with rates in 1999, suicide rates in 2017 were higher for males and females in all age groups from 10 to 74 years. The differences in age-adjusted suicide rates between the most rural (noncore) and most urban (large central metro) counties was greater in 2017 than in 1999. In 1999, the age-adjusted suicide rate for the most rural counties (13.1 per 100,000) was 1.4 times the rate for the most urban counties (9.6), while in 2017, the age-adjusted suicide rate for the most rural counties (20.0) was 1.8 times the rate for the most urban counties (11.1). The age-adjusted suicide rate for the most urban counties in 2017 (11.1 per 100,000) was 16% higher than the rate in 1999 (9.6), while the rate for the most rural counties in 2017 (20.0) was 53% higher than the rate in 1999 (13.1).Data sources and methods
Data were analyzed using the NVSS multiple cause-of-death mortality files for 1999 through 2017 (5). Suicide deaths were identified using International Classification of Diseases, Tenth Revision (ICD–10) underlying cause-of-death codes U03, X60–X84, and Y87.0 (6). Age-adjusted death rates were calculated using the direct method and the 2000 U.S. standard population (7). Suicides for persons aged 5–9 years were included in the total numbers and age-adjusted rates but not shown as part of the age-specific numbers or rates, due to the small number of suicide deaths among this age group. Urbanization level of the decedent’s county of residence was categorized using the 2006 NCHS Urban–Rural Classification Scheme for Counties (8). Counties were classified into six urbanization levels based on metropolitan–nonmetropolitan status, population distribution, and other factors. The six urbanization levels ranged from the most urban (large central metro) to the most rural (noncore). Metropolitan counties include large central counties, the fringes of large counties (suburbs), medium counties, and small counties. Nonmetropolitan counties (i.e., rural counties) include micropolitan statistical areas and noncore areas, including open countryside, rural towns (populations of less than 2,500), and areas with populations of 2,500–49,999 that are not part of larger labor market areas (metropolitan areas). Trends in age-adjusted death rates were evaluated using the Joinpoint Regression Program .The Joinpoint software was used to fit weighted least-squares regression models to the estimated proportions on the linear scale. The default settings allowed for as few as four observed time points in the beginning, ending, and middle line segments, including the joinpoints. Using these settings, a maximum of three joinpoints were searched for using the grid search algorithm and permutation test, and an overall alpha level of 0.05 . Pairwise comparisons of rates in Figures 2–4 were conducted using the z test statistic with an alpha level of 0.05 .About the authors
