21. Notably, Brazil s birth rate is well below the replacement rate of 2.1 children per woman. 22. Since turtles are slow to sexually mature and are long-lived, they generally have poor replacement rates when hunted. 23. Replacement rate dropped below zero in the 1970s when the government was urging parents, " Stop at two ."24. Nowadays many ewes are housed indoors for lambing, which costs more but facilitates earlier lambing with lower mortality and replacement rates . 25. Because the turtles are long-lived, with lower replacement rates than typical game, concerns exist for over-harvesting. 26. They also modeled the painted turtles'replacement rate and suggested that unrestricted harvest put the populations in danger of dropping strongly. 27. The U . S . figure is barely 2.0, and it has been below the replacement rate for 30 years. 28. They say that continuous access to a 401 ( k ) plan is the most significant factor affecting projected income replacement rates at retirement. 29. For example, the replacement rate in Missouri is 55.4 %, while in New York it is 77.1 %. 30. The current birth rate in Brazil is at a replacement rate of about 2.18 births per woman estimated for the year 2011.
