what is considered middle age in the united states
Middle age According to the Oxford English Dictionary middle age is between 45 and 65:[2] "The period between early adulthood and old age, usually considered as the years from about 45 to 65." The US Census lists the category middle age from 45 to 65. Merriam-Webster list middle age from 45 to 64,[3] while prominent psychologist Erik Erikson saw it starting a little earlier and defines middle adulthood as between 40 and 65. The Collins English Dictionary, list it between the ages of 40 and 60.[4] and the Diagnostic and Statistical Manual of Mental Disorders - the standard diagnostic manual of the American Psychiatric Association - used to define middle age as 40 to 60, but as of DSM-IV (1994) revised the definition upwards to 45 to 65.
Middle Ages The most commonly given starting point for the Middle Ages is 476,[11] first used by Bruni.[5][A] For Europe as a whole, 1500 is often considered to be the end of the Middle Ages,[13] but there is no universally agreed upon end date. Depending on the context, events such as Christopher Columbus's first voyage to the Americas in 1492, the conquest of Constantinople by the Turks in 1453, or the Protestant Reformation in 1517 are sometimes used.[14] English historians often use the Battle of Bosworth Field in 1485 to mark the end of the period.[15] For Spain, dates commonly used are the death of King Ferdinand II in 1516, the death of Queen Isabella I of Castile in 1504, or the conquest of Granada in 1492.[16] Historians from Romance-speaking countries tend to divide the Middle Ages into two parts: an earlier "High" and later "Low" period. English-speaking historians, following their German counterparts, generally subdivide the Middle Ages into three intervals: "Early", "High", and "Late".[1] In the 19th century, the entire Middle Ages were often referred to as the "Dark Ages",[17][B] but with the adoption of these subdivisions, use of this term was restricted to the Early Middle Ages, at least among historians.[2]
