Sexism occurs on three levels namely, institutionalized sexism, interpersonal sexism and internalized sexism. Institutionalized sexism occurs when sexism is woven into political, social, and economic institutions. Interpersonal sexism occurs on a more individual scale within interpersonal interactions. Women and girls make up more than half of the world’s population. Though the cultural communities they inhabit vary dramatically, sexism nonetheless is built into every community’s cultural norms and practices, its moral code, its notions of common sense, and often into its laws as well. Historically, sexism has taken a number of overt and undeniable forms, most of them instances of institutionalized sexism. Discrimination prevents women from holding certain jobs, and in other communities makes it more difficult for women to secure positions. Leadership positions in business and in government are disproportionately occupied by men.
