Third Church of Christ, Scientist, established in 1918, is a Christian Science church in downtown Washington, D.C. From 1971 to 2014, the church was located in a controversial building at 16th and I Street NW. Considered a significant work of "Brutalist" church architecture by some critics, the building was considered unsatisfactory by members of the Church's congregation, which shrank over the years. In 2007, the church applied for a demolition permit for the building to permit sale and redevelopment of the site, with plans to relocate to a more suitable structure. A 1991 application for landmark status for the building, filed to forestall a demolition threat then, was subsequently approved. After a lawsuit and hearings, the District of Columbia issued a demolition permit in May 2009, and the building was demolished in 2014. In 2015, Third Church merged with First Church of Christ, Scientist. The congregation continues as First Church and conducts its activities in a portion of the new building.

As of June 2020, the VA employs 412,892 people at hundreds of Veterans Affairs medical facilities, clinics, benefits offices, and cemeteries. In Fiscal Year 2016 net program costs for the department were $273 billion, which includes the VBA Actuarial Cost of $106.5 billion for compensation benefits. The long-term "actuarial accrued liability" (total estimated future payments for veterans and their family members) is $2.491 trillion for compensation benefits; $59.6 billion for education benefits; and $4.6 billion for burial benefits.
