Development should be measured by capabilities, meaning the real freedoms a person has to achieve the functionings they have reason to value, such as being nourished, literate, mobile, or able to take part in community life. Income is only an instrument. The same income converts into very different capabilities depending on disability, climate, disease burden, and social setting.
No substantial famine has occurred in a functioning democracy with regular elections, opposition parties, and a relatively free press. Famines are cheap to prevent, and a free press and electoral accountability make it politically costly for rulers to let them happen. India has had no major famine since independence, while China's 1958–61 famine killed around 30 million people without public correction.
Famines often happen without any decline in total food supply. They occur when particular groups lose their entitlements, meaning their command over food through wages, prices, or assets. In the 1943 Bengal famine, food output was not unusually low. Wartime inflation collapsed the purchasing power of rural laborers while others bid up food prices, so the analysis should track who can obtain food, not how much food exists.
Five types of freedom act as means of development and strengthen one another: political freedoms, economic facilities, social opportunities such as education and health, transparency guarantees, and protective security. Progress in one expands the others. Basic education, for example, improves economic participation, political voice, and health outcomes together.
The Indian state of Kerala had very low per-capita income but achieved life expectancy comparable to far richer countries, through public education, healthcare, and female literacy. African Americans in the US had much higher incomes yet lower survival chances at older ages than people in Kerala or China. Income rankings and survival rankings can diverge sharply, depending on how public resources are deployed.
Expanding women's agency, through female literacy, independent earnings, and property rights, is one of the most powerful levers for reducing child mortality and fertility and for correcting the 'missing women' caused by sex-biased neglect. Women with more voice within the household shift resource allocation toward child survival and away from unwanted births. This makes them active agents of change, not just recipients of welfare.
