[email protected] 1 Mortality in the United Kingdom – 20th century trends During the course of the 20th century, the United Kingdom saw a continuation of the pattern of falling death rates that began around the beginning of the 19th century. Over these two centuries there has been a change from a regime of high infant and child mortality, with a preponderance of acute and infectious diseases, to a new regime in which adult mortality predominates and chronic and degenerative diseases are the most common causes of death. Period life expectancy at birth in the mid-19th century was around 40 years for males and 42 years for females. These figures increased to around 45 and 50 years respectively by 1901. Life expectancy then rose dramatically until the mid- 1950s. Since then, life expectancy at birth has continued to increase but at a less rapid rate (see Fig 1). Life expectancy for males rose at a lower rate than for females during the 1950s and 1960s, with the difference between males and females rising to a high of 6.3 years in 1970. Since 1970, male expectation of life has been increasing faster than female and the differential has fallen to 4.4 years by 2003.
