  Modern scientific surveys find that, across cultures, most people report a heterosexual orientation. Bisexuality comes in varying degrees of relative attraction to the same or opposite sex. Men are more likely to be exclusively homosexual than to be equally attracted to both sexes, while the opposite is true for women.
  
  Surveys in Western cultures find, on average, that about 93% of men and 87% of women identify as completely heterosexual, 4% of men and 10% of women as mostly heterosexual, 0.5% of men and 1% of women as evenly bisexual, 0.5% of men and 0.5% of women as mostly homosexual, and 2% of men and 0.5% of women as completely homosexual. An analysis of 67 studies found that the lifetime prevalence of sex between men (regardless of orientation) was 3-5% for East Asia, 6-12% for South and South East Asia, 6-15% for Eastern Europe, and 6-20% for Latin America. The International HIV/AIDS Alliance estimates a worldwide prevalence of men who have sex with men between 3 and 16%.
  
  The relative percentage of the population that reports a homosexual or bisexual orientation can vary with different methodologies and selection criteria. A 1998 report stated that these statistical findings are in the range of 2.8 to 9% for males, and 1 to 5% for females for the United States – this figure can be as high as 12% for some large cities and as low as 1% for rural areas.
  
  A small percentage of people are not sexually attracted to anyone (asexuality). A study in 2004 placed the prevalence of asexuality at 1%.
