Another example of violation of human dignity, especially for women in developing countries, is lack of sanitation. Having no access to toilets leaves currently about 1 billion people of the world with no choice other than to defecation in the open, which has been declared by the Deputy Secretary-General of the United Nations as an affront to personal dignity. Human dignity is also violated by the practice of employing people in India for "manual scavenging" of human excreta from unsanitary toiletsusually by people of a lower caste, and more often by women than men.
