natural increase = birth rate-death rate. The rate of natural increase is given as a percentage, calculated by dividing the natural increase by 10. For example, if the birth rate is 14 per 1,000 population, and the death rate is 8 per 1000 population, then the natural increase = 14 - 8 = 6.
Patty Duke Has Died. Former child star, Oscar winner, cult movie idol and overall Hollywood legend Patty Duke died early this morning. She was 69. Patty Dukeâs son Sean Astin (aka Samwise in The Lord of the Rings movies) confirmed the sad news on Facebook by posting a statement from his family. Patty Duke (born name: Anna Marie Duke) died from sepsis from a ruptured intestine.
Duke had been living in Idaho for the past 28 years with her current husband, Michael Pierce â her fourth husband, to be exact. Answering who was Patty Duke married to is a bit of a loaded question, as Duke's love life was one of much drama throughout her life. Born Anna Marie, Duke was best known for her Academy Award-winning role as Helen Keller in the 1962 film, The Miracle Worker, when she was only 16 years old.
