the records of the lds church show membership growth every decade since its beginning in the 1830s. following initial growth rates that averaged 10% to 25% per year in the 1830s through 1850s, it grew at about 4% per year through the last four decades of the 19th century. after a steady slowing of growth in the first four decades of the 20th century to a rate of about 2% per year in the 1930s (the great depression years), growth boomed to an average of 6% per year for the decade around 1960, staying around 4% to 5% through 1990. after 1990, average annual growth again slowed steadily to a rate around 2.2% for the ten years ending 2015, approximately double the average world population growth rate of 1.1% for the same period. the growth rate has not been greater than 3% per year in the 21st century and has declined steadily since 2012. the rate has not been above 2% since 2013.

section::::cell culture doubling time.









































cell doubling time can be calculated in the following way using growth rate (amount of doubling in one unit of time)
