Note: This table measures "undernourishment", as defined by the FAO, and represents the number of people consuming (on average for years 2010 to 2012) less than the minimum amount of food energy (measured in kilocalories per capita per day) necessary for the average person to stay in good health while performing light physical activity. It is a conservative indicator that does not take into account the extra needs of people performing extraneous physical activity, nor seasonal variations in food consumption or other sources of variability such as inter-individual differences in energy requirements. Malnutrition and undernourishment are cumulative or average situations, and not the work of a single day's food intake (or lack thereof). This table does not represent the number of people who "went to bed hungry today."

The below is a list of countries by percentage of population with undernourishment, as defined by the {{wipe|United Nations}} [[Organization:World Food Programme|World Food Programme]] and the FAO in its "The State of Food Insecurity in the World" 2009 report.

Research on overcoming persistent under-nutrition published by the Institute of Development Studies, argues that the co-existence of India as an 'economic powerhouse' and home to one-third of the world's under-nourished children reflects a failure of the governance of nutrition: "A poor capacity to deliver the right services at the right time to the right populations, an inability to respond to citizens' needs and weak accountability are all features of weak nutrition governance."<ref name=curse>{{cite journal|url=http://www.ids.ac.uk/idspublication/lifting-the-curse-overcoming-persistent-undernutrition-in-india|title=Lifting the Curse: Overcoming Persistent Undernutrition in India|journal=IDS Bulletin|volume=40|issue=4|date=2009-07-02|author1=Haddad, L.|author2=Zeitlyn, S.|pages=1–8|doi=10.1111/j.1759-5436.2009.00052.x|access-date=2013-03-21|archive-url=https://web.archive.org/web/20170331212145/http://www.ids.ac.uk/idspublication/lifting-the-curse-overcoming-persistent-undernutrition-in-india|archive-date=2017-03-31|url-status=dead}}</ref> The research suggests that to make under-nutrition history in India the governance of nutrition needs to be strengthened and new research needs to focus on the politics and governance of nutrition.

Although the United States Department of Agriculture reported in 2012 that an estimated 85.5 percent of households in the country are food secure, millions of people in America struggle with the threat of hunger or experience hunger on a daily basis.<ref name="USDA Report 2012">{{cite journal|last1=Coleman-Jensen|first1=A|last2=Nord|first2=M|last3=Singh|first3=A|title=Household Food Security in the United States in 2012|date=2013|journal=U.S. Department of Agriculture}}</ref> The USDA defines [[Earth:Food security|food security]] as the economic condition of a household wherein which there is reliable access to a sufficient amount of food so all household members can lead a healthy productive life.<ref name="Hunger in America 2014: Executive Summary">{{cite journal|last1=Borger|first1=C|last2=Gearing|first2=M|last3=Macaluso|first3=T|last4=Mills|first4=G|last5=Montaquila|first5=J|author5-link= Jill DeMatteis |last6=Weinfield|first6=N|last7=Zedlewski|first7=S|title=Hunger in America 2014: Executive Summary|date=2014|journal=Feeding America}}</ref> Hunger is most commonly related to poverty since a lack of food helps perpetuate the [[Finance:Cycle of poverty|cycle of poverty]]. Most obviously, when individuals live in poverty they lack the financial resources to purchase food or pay for unexpected events, such as a medical emergency. When such emergencies arise, families are forced to cut back on food spending so they can meet the financial demands of the unexpected emergency.<ref name="Q & A: The Causes Behind Hunger in America">{{cite web|last1=Valentine|first1=Vikki|title=Q & A: The Causes Behind Hunger in America|url=https://www.npr.org/2005/11/22/5021812/q-a-the-causes-behind-hunger-in-america|website=NPR|access-date=19 October 2014|archive-date=30 October 2018|archive-url=https://web.archive.org/web/20181030131222/https://www.npr.org/2005/11/22/5021812/q-a-the-causes-behind-hunger-in-america|url-status=live}}</ref> There is not one single cause of hunger but rather a complex interconnected web of various factors.

The largest nonprofit food relief organization in the United States, Feeding America, feeds 46.5 million citizens a year to address the nation's food insecurity issue.<ref name="Hunger in America 2014: Executive Summary" /> This equates to one in seven Americans requiring their aid in a given year. An organization that focuses on providing food for the elderly population is Meals on Wheels, which is a nonprofit that delivers meals to seniors' homes. The government also works towards providing relief through programs such as the Supplemental Nutrition Assistance Program (SNAP) which was formerly known to the public as Food Stamps. Another well known government program is the National School Lunch Program (NSLP) which provides free or reduced lunches to students who qualify for the program.

The number of Americans suffering from hunger rose after the 2008 financial crisis, with children and working adults now making up a large proportion of those affected. In 2012, ''Gleaners Indiana Food bank'' reported that there were now 50 million Americans struggling with food insecurity (about 1 in 6 of the population), and that the number of folks seeking help from food banks had increased by 46% since 2005.<ref>[http://www.gleaners.org/ Gleaners Indiana Food bank] {{Webarchive|url=https://web.archive.org/web/20220325142147/https://www.gleaners.org/ |date=2022-03-25 }} Retrieved 18 July 2012</ref> According to a 2012 study by UCLA Center for Health Policy Research, even married couples who both work but have low incomes sometimes require the aid of food banks.<ref>{{cite web |url=http://www.loansafe.org/thousands-more-in-solano-napa-counties-are-turning-to-food-banks  |title=Thousands More in Solano, Napa Counties are Turning to Food Banks  |author=Alex Ferreras  |date=11 July 2012  |access-date=11 July 2012  |url-status=dead  |archive-url=https://web.archive.org/web/20120717045016/http://www.loansafe.org/thousands-more-in-solano-napa-counties-are-turning-to-food-banks  |archive-date=17 July 2012  |df=dmy-all }}</ref><ref>{{cite news|url= https://www.theguardian.com/commentisfree/2012/sep/20/poverty-hunger-america|title= Poverty and hunger in America|work= {{wipe|The Guardian}}|author= John Turner|date= 20 September 2012|access-date= 1 October 2012|archive-date= 14 July 2019|archive-url= https://web.archive.org/web/20190714162516/https://www.theguardian.com/commentisfree/2012/sep/20/poverty-hunger-america|url-status= live}}</ref>

Childhood malnutrition is generally thought of as being limited to developing countries, but although most malnutrition occurs there, it is also an ongoing presence in developed nations. For example, in the United States of America, one out of every six children is at risk of hunger.{{Citation needed|date=July 2011}} A study, based on 2005–2007 data from the U.S. Census Bureau and the Agriculture Department, shows that an estimated 3.5 million children under the age of five are at risk of hunger in the United States.<ref>{{cite news | title=3.5M Kids Under 5 On Verge Of Going Hungry<br />Study: 11 Percent Of U.S. Households Lack Food For Healthy Lifestyle | url=http://www.cbsnews.com/stories/2009/05/07/health/main4998190.shtml | work=Health | publisher=CBS NEWS | date=2009-05-07 | access-date=2009-05-08 | archive-date=2013-05-13 | archive-url=https://web.archive.org/web/20130513155419/http://www.cbsnews.com/stories/2009/05/07/health/main4998190.shtml | url-status=live }}</ref>

In developed countries, this persistent hunger problem is not due to lack of food or food programs, but is largely due to an underutilization of existing programs designed to address the issue, such as food stamps or [[Social:School meal|school meal]]s. Many citizens of rich countries such as the United States of America attach stigmas to food programs or otherwise discourage their use. In the USA, only 60% of those eligible for the food stamp program actually receive benefits.<ref name="plan_to_end_childhood_hunger_in_america">{{cite web |url=http://strength.org/childhood_hunger/our_plan |title=Plan to End Childhood Hunger in America |publisher=Share Our Strength |year=2009 |url-status=dead |archive-url=https://web.archive.org/web/20110729002514/http://strength.org/childhood_hunger/our_plan/ |archive-date=2011-07-29 }}</ref>

The U.S. Department of Agriculture reported that in 2003, 1 out of 200 U.S. households with children were so severely food insecure that any of the children went hungry at least once during the year. A substantially larger proportion of these same households (3.8 percent) had adult members who were hungry at least one day during the year because of their households' inability to afford enough food.<ref>{{Cite web |url=http://www.ers.usda.gov/amber-waves/2005-april/data-feature.aspx |title=USDA ERS - Data Feature |access-date=2015-05-12 |archive-url=https://web.archive.org/web/20150519183206/http://www.ers.usda.gov/amber-waves/2005-april/data-feature.aspx |archive-date=2015-05-19 |url-status=dead }}</ref>
