Poverty can be defined in several ways such as relative poverty, which compares incomes to the average, and absolute poverty, which looks at having enough for basic needs. Poverty is measured using indicators like the low income cut-off and depth and duration of living below this level. In Canada in 2009, 3.2 million people lived below the low income cut-off. Causes of poverty include income inequality, costs of living, types of available jobs, and certain groups like women and indigenous people facing higher risks. Experiencing poverty can negatively impact people's physical and mental health as well as social opportunities.
