paragraph_text: Demographic factors
  
  Gender, age, ethnicity, life expectancy, longevity, population density, and community diversity are all demographic characteristics that can increase the risk and severity of mental disorders. Existing evidence demonstrates that the female gender is connected with an elevated risk of depression at differerent phases of life, commencing in adolescence in different contexts. Females, for example, have a higher risk of anxiety and eating disorders, whereas males have a higher chance of substance abuse and behavioural and developmental issues. This does not imply that women are less likely to suffer from developmental disorders such autism spectrum disorder, attention deficit hyperactivity disorder, Tourette syndrome, or early-onset schizophrenia. Ethnicity and ethnic heterogeneity have also been identified as risk factors for the prevalence of mental disorders, with minority groups being at a higher risk due to discrimination and exclusion.
  
  Unemployment has been shown to hurt an individual's emotional well-being, self-esteem, and more broadly their mental health. Increasing unemployment has been shown to have a significant impact on mental health, predominantly depressive disorders. This is an important consideration when reviewing the triggers for mental health disorders in any population survey. According to a 2009 meta-analysis by Paul and Moser, countries with high income inequality and poor unemployment protections experience worse mental health outcomes among the unemployed.
  
  Emotional mental disorders are a leading cause of disabilities worldwide. Investigating the degree and severity of untreated emotional mental disorders throughout the world is a top priority of the World Mental Health (WMH) survey initiative, which was created in 1998 by the World Health Organization (WHO). " Neuropsychiatric disorders are the leading causes of disability worldwide, accounting for 37% of all healthy life years lost through disease. These disorders are most destructive to low and middle-income countries due to their inability to provide their citizens with proper aid. Despite modern treatment and rehabilitation for emotional mental health disorders, "even economically advantaged societies have competing priorities and budgetary constraints".
  
  Unhappily married couples suffer 3–25 times the risk of developing clinical depression.
  
  The World Mental Health survey initiative has suggested a plan for countries to redesign their mental health care systems to best allocate resources."A first step is documentation of services being used and the extent and nature of unmet treatment needs. A second step could be to do a cross-national comparison of service use and unmet needs in countries with different mental health care systems. Such comparisons can help to uncover optimum financing, national policies, and delivery systems for mental health care."
  
  Knowledge of how to provide effective emotional mental health care has become imperative worldwide. Unfortunately, most countries have insufficient data to guide decisions, absent or competing visions for resources, and near-constant pressures to cut insurance and entitlements. WMH surveys were done in Africa (Nigeria, South Africa), the Americas (Colombia, Mexico, United States), Asia and the Pacific (Japan, New Zealand, Beijing and Shanghai in the People's Republic of China), Europe (Belgium, France, Germany, Italy, Netherlands, Spain, Ukraine), and the Middle East (Israel, Lebanon). Countries were classified with World Bank criteria as low-income (Nigeria), lower-middle-income (China, Colombia, South Africa, Ukraine), higher middle-income (Lebanon, Mexico), and high-income.
  
  The coordinated surveys on emotional mental health disorders, their severity, and treatments were implemented in the aforementioned countries. These surveys assessed the frequency, types, and adequacy of mental health service use in 17 countries in which WMH surveys are complete. The WMH also examined unmet needs for treatment in strata defined by the seriousness of mental disorders. Their research showed that "the number of respondents using any 12-month mental health service was generally lower in developing than in developed countries, and the proportion receiving services tended to correspond to countries' percentages of gross domestic product spent on health care"."High levels of unmet need worldwide are not surprising, since WHO Project ATLAS ' findings of much lower mental health expenditures than was suggested by the magnitude of burdens from mental illnesses. Generally, unmet needs in low-income and middle-income countries might be attributable to these nations spending reduced amounts (usually <1%) of already diminished health budgets on mental health care, and they rely heavily on out-of-pocket spending by citizens who are ill-equipped for it".
