Waist–hip ratio
WHR is used as a measurement of obesity, which in turn is a possible indicator of other more serious health conditions. The WHO states that abdominal obesity is defined as a waist-hip ratio above 0.90 for males and above 0.85 for females, or a body mass index (BMI) above 30.0. The National Institute of Diabetes, Digestive and Kidney Diseases (NIDDK) states that women with waist-hip ratios of more than 0.8, and men with more than 1.0, are at increased health risk because of their fat distribution.
Head count ratio
The Head count ratio (HCR) is the proportion of a population that exists, or lives, below the poverty line. The Poverty headcount ratio at national poverty line (percentage of population) in India was last reported at 21.9% in 2011-12.
Definition:-When the number of poor is estimated as the proportion of people below the poverty line, it is known as 'head count ratio'.
