One American study showed that "even in areas with safe tap water, African American and Latino parents were three times more likely to give their children mostly bottled water compared to non-Latino white children, because of their belief that bottled water is safer, cleaner, better tasting, or more convenient." The economic implications of this also showed serious inequities: as a percentage of household income, whites reported median spending of 0.4% of their income on bottled water; African Americans and Latinos reported median spending to be more than twice as high.” The study volunteers, "For poor families, the use of bottled water may lead to less availability of resources for other health needs...by the rather striking levels of expenditure on water relative to household income." On a global scale, markets for bottled water in poorer developing countries are growing rapidly due to increased fears of “contaminated tap water, inadequate municipal water systems, and increased marketing on the part of bottled water companies.” Sales of bottled water in Mexico, China, and parts of India are rising steeply.
