In 2011, the Ecology Global Network estimated that 151,600 people across the world died each day, with roughly eight deaths in every population of 1,000. Nearly two people die each second, or 105 people every minute. The average life expectancy at birth is calculated to be 67 years.
World birth rates in 2011 averaged at 360,000 births per day, according to the Ecology Global Network, which is over twice the death rate.
In 2013, the CDC announced that there had been 2,596,993 deaths in the United States, with an average life expectancy of 78.8 years. Heart disease was the leading cause of death, causing 611,105 deaths, with cancer following at 584,881. Accidents contributed to 130,557 deaths. The infant mortality rate in 2013 was 5.96 deaths per 1,000 live births. Intentional self-harm, or suicide, was responsible for 41,149 deaths.
Mortality data in the United States is collected through the National Vital Statistics System or NVSS, according to the CDC. The NVSS uses standard forms to collect data and provide demographic, geographic and cause-of-death information. The data is also used to examine how the United States compares in mortality rates across the globe as well as to determine life expectancy and track any trends or characteristics among the dying.
