Adventists run a large number of hospitals and health-related institutions. Their largest medical school and hospital in North America is Loma Linda University and its attached Medical Center. Throughout the world, the church runs a wide network of hospitals, clinics, lifestyle centers, and sanitariums. These play a role in the church's health message and worldwide missions outreach.[90]
The Metropolitan Transit Authority of Harris County (METRO) provides public transportation in the form of buses, light rail, high-occupancy vehicle (HOV) lanes, and paratransit to fifteen municipalities throughout the Greater Houston area and parts of unincorporated Harris County. METRO's service area covers 1,303 square miles (3,370 km2) containing a population of 3.6 million.[271]
As of December 31, 2016, the church has 20,008,779 baptized members.[2] Between 2005 and 2015, around half a million people per year have joined the Adventist church, through baptisms and professions of faith.[2][78] The church is one of the world's fastest-growing organizations, primarily from membership increases in developing nations. Today, less than 7% of the world membership reside in the United States, with large numbers in Africa as well as Central and South America. Depending on how the data was measured, it is reported that church membership reached 1 million between 1955 and 1961, and grew to five million in 1986. At the turn of the 21st century the church had over 10 million members, which grew to over 14 million in 2005, 16 million in 2009, and 19 million in 2015.[79] It is reported that today over 25 million people worship weekly in Seventh-day Adventist churches worldwide.[80] The church operates in 202 out of 230 countries and areas recognized by the United Nations,[2] making it "probably the most widespread Protestant denomination".[81]
A variety of Eastern and Oriental Orthodox churches can be found in Houston. Immigrants from Eastern Europe, the Middle East, Ethiopia, India and other areas have added to Houston's Eastern and Oriental Orthodox population. As of 2011 in the entire State of Texas there were 32,000 people who actively attend Orthodox churches.[136] In 2013 Father John Whiteford, the pastor of St. Jonah Orthodox Church near Spring, stated that there were about 6,000-9,000 Eastern Orthodox Christians in Houston.[137]
Because of this diet, many experts have said Seventh Day Adventists can live an average of 10 years longer than most Americans. In a study from Loma Linda University, scientists found that Adventists can die of cancer, stroke or heart disease, but the age at which those diseases and illnesses are diagnosed is much later because of their healthy lifestyle and resting on the Sabbath.
METRO began light rail service in 2004 with the opening of the 8-mile (13 km) north-south Red Line connecting Downtown, Midtown, the Museum District, the Texas Medical Center, and NRG Park. In the early 2010s, two additional lines—the Green Line, servicing the East End, and the Purple Line, servicing the Third Ward—opened, and the Red Line was extended northward to Northline, bringing the total length of the system to 22.7 miles (36.5 km). Two light rail lines outlined in a five-line system approved by voters in a 2003 referendum have yet to be constructed.[273] The Uptown Line, which would run along Post Oak Boulevard in Uptown, is currently under construction as a bus rapid transit line—the city's first—while the University Line has been postponed indefinitely.[274] The light rail system saw approximately 16.8 million boardings in fiscal year 2016.[271]
Houston's murder rate ranked 46th of U.S. cities with a population over 250,000 in 2005 (per capita rate of 16.3 murders per 100,000 population).[228] In 2010, the city's murder rate (per capita rate of 11.8 murders per 100,000 population) was ranked sixth among U.S. cities with a population of over 750,000 (behind New York City, Chicago, Detroit, Dallas, and Philadelphia)[229] according to the Federal Bureau of Investigation (FBI).
