Houston was estimated to be over 40,000. Grainne O'Reilly-Askew, the first headmistress of the British School of Houston, said that before the school was established, British companies encountered difficulty in convincing their executives to relocate to Greater Houston, since the area previously did not have a school using the British educational system. John Major, the former Prime Minister of the United Kingdom, attended the school's official opening. Circa 2013 the Houston area had about 98,300 people of Middle Eastern origins, with a margin of error of more than 27,700. This figure includes people of Arab, Iranian, Israeli, and Turkish origins. Iranians/Persians As of 1994, over 50,000 ethnic Iranians live in Houston. As of that year, 12 city blocks along Hillcroft Avenue, from Westheimer Road to a point just south of Westpark, contain a Persian business district including shops and restaurants. Allison Cook of the Houston Press referred to the area as "Little Persia". As of 1990 most Iranians/Persians in Houston are not religious.

By 2000 some Muslim Iranians who were opposed to fundamentalism in the mosques, began attending Zoroastrian events. Rustomji wrote in 2000 that from 2000 to 2005, Iranians were expected to make up a greater proportion of ZAH. As of 2006, most member of the Houston Haziratu'l-Quds (a Baháʼí Faith center) were Persians. As of 2010 many Houston Baháʼí are refugees from Iran.
