Natality in population ecology is the scientific term for birth rate.
 Along with mortality rate, natality rate is used to calculate the dynamics of a population.
 They are the key factors in determining whether a population is increasing, decreasing or staying the same in size.
 Natality is the greatest influence on a population’s increase.
 Natality is shown as a crude birth rate or specific birth rate.
 Crude birth rate is used when calculating population size (number of births per 1000 population/year), whereas specific birth rate is used relative to a specific criterion such as age.
 By calculating specific birth rate, the results are seen in an age-specific schedule of births.
Janet Balaskas is an author, founder of the Active Birth Movement, and childbirth educator.
 She is perhaps known best for her advocacy of "active birth" where the woman is free to move during labour, rather than being placed into stirrups or the lithotomy position.
 She coined the term "active birth" which she explained in the first of her books "Active Birth" published in 1983.
Henci Goer is an American author who writes about pregnancy and childbirth.

 Previously appearing on ParentsPlace.com as the “Birth Guru,” she is currently a resident expert for the Lamaze Institute for Normal Birth Forum.
 Now concentrating on writing and speaking, Goer was a doula (labor support professional) for over 20 years and a "Lamaze", (private interest) educator for ten.
Iran had a comprehensive and effective program of family planning since the beginning of the 1990s.
 While Iran's population grew at a rate of more than 3% per year between 1956 and 1986, the growth rate began to decline in the late 1980s and early 1990s after the government initiated a major population control program.
 By 2007 the growth rate had declined to 0.7 percent per year, with a birth rate of 17 per 1,000 persons and a death rate of 6 per 1,000.
 Reports by the UN show birth control policies in Iran to be effective with the country topping the list of greatest fertility decreases.
 UN's Population Division of the Department of Economic and Social Affairs says that between 1975 and 1980, the total fertility number was 6.5.
 The projected level for Iran's 2005 to 2010 birth rate is fewer than two.
Lumbini Development Trust (1985) or (लुम्बिनी बिकाश कोष) was founded for the purposes of restoring the Lumbini Garden under the master plan of the government of Nepal.
 Lumbini is the traditional birthplace of Gautama Buddha, the founder of Buddhism, who was born in the 7th or 6th century BC.According to Buddhist tradition, Maya Devi (or Mayadevi) gave birth to the Buddha on her way to her parent's home in Devadaha in the month of May in the year 623 BC.
 Feeling the onset of labor pains, she grabbed hold of the branches of a shade tree and gave birth to Siddharta Gautama, the future Buddha.
 The Buddha is said to have announced, "This is my final rebirth" as he entered the world.
 Buddhist tradition also has it that he walked immediately after his birth and took seven steps, under each of which a lotus flower bloomed.
 In 249 BC, the Buddhist convert Emperor Ashoka visited Lumbini and constructed four stupas and a stone pillar.
 Ashoka's Pillar bears an inscription that translates as: "King Piyadasi (Ashoka), beloved of devas, in the 20 year of the coronation, himself made a royal visit, Buddha Sakyamuni having been born here, a stone railing was built and a stone pillar erected to the Bhagavan ["blessed one"] having been born here.
 Lumbini village was taxed reduced and entitled to the eight part (only)".
Müller was born in 1740 or 1742 in the Habsburg Empire.
 While the "Allgemeine Deutsche Biographie" gives 1 July 1740 and Vienna as date and place of birth, the "Neue Deutsche Biographie" prefers 4 October 1742 and the small town of Poysdorf in Lower Austria.
 The much older works "Neuer Nekrolog der Deutschen" and "Oesterreichische National-Encyklopädie" do not give a place of birth and only the year 1740 for his birth.
 Even articles by Mary Elvira Weeks on the discovery of tellurium, published in the Journal of Chemical Education in 1932, and 1935 quote two different locations of his birth: one in Vienna and the other Hermannstadt (Sibiu) Transylvania, present day Romania.
 A newer biography on the topic makes clear that date and place of birth are not definitely known.
Averroes wrote a medical encyclopedia called "Kulliyat (Colliget)" ("Generalities", i. e. general medicine), known in its Latin translation as "Colliget".
Life expectancy is a statistical measure of the average time an organism is expected to live, based on the year of their birth, their current age and other demographic factors including sex.
 The most commonly used measure of life expectancy is at birth (LEB), which can be defined in two ways.
 "Cohort" LEB is the mean length of life of an actual birth cohort (all individuals born a given year) and can be computed only for cohorts born many decades ago, so that all their members have died.
 "Period" LEB is the mean length of life of a hypothetical cohort assumed to be exposed, from birth through death, to the mortality rates observed at a given year.
Ibn Rushd (Arabic: ‎ ‎ ; 14 April 1126 – 10 December 1198), full name (Arabic: أبو الوليد محمد ابن احمد ابن رشد‎ , "ʾAbū l-Walīd Muḥammad Ibn ʾAḥmad Ibn Rushd " ‎ ), often Latinized as Averroes ( ), was a medieval Andalusian polymath.
 He wrote on logic, Aristotelian and Islamic philosophy, theology, the Maliki school of Islamic jurisprudence, psychology, political and Andalusian classical music theory, geography, mathematics, and the mediæval sciences of medicine, astronomy, physics, and celestial mechanics.
 Ibn Rushd was born in Córdoba, Al Andalus (present-day Spain), and died at Marrakesh in present-day Morocco.
 His body was interred in his family tomb at Córdoba.
 The 13th-century philosophical movement in Latin Christian and Jewish tradition based on Ibn Rushd's work is called Averroism.
Matthew Buchanan is a fictional character on the American soap opera "One Life to Live".
 Born onscreen in 1999, the character was rapidly aged in 2001 with the casting of Eddie Alderson, re-establishing his birth year as 1994 (which is also Alderson's birth year).
 Alderson stayed with the series until the ABC Daytime finale in 2012.
 Upon resuming as a web series via The Online Network, Robert Gorrie was cast in the role and debuted April 29, 2013, ultimately revising his birth year to 1992.
