The Bahai community is very widely spread across the world, but in small numbers. Most local Bahai communities meet in private homes, or in a rented hall or a Bahai centre, and the same places are used for worship meetings and other meetings.
However specially dedicated Houses of Worship / Temples / Mashriq'ul-Adhkars (3 names for the same thing) have been built in some places. There are continental Houses of Worship (for example, the North American one in Wilmette, Illinois) and two national ones are about to be built (Congo and Papua New Guinea).
Local communities, especially in the third world, may have a small house of worship or Bahai centre built with local resources, and plans for a number of smaller Houses of Worship have recently been announced in Cambodia, India, Kenya, Colombia and Vanuatu. These will be built with help from the Bahais around the world, and will be in permanent materials.
A Bahai place of worship is called: 1) a Bahai house of worship, 2) a Bahai temple or 3) a Mashriqu'l-adhkar These are three different names for the same thing.
A Bahá'í believer can worship, or pray, anywhere - at home for example. However, there are usually designated places in each town or city, where Bahá'ís meet to pray, to consult, etc.
There are Bahá'ís all over the world, in every country.
