Texas also has a large population of Iranian descent. And like California, Iranians in Texas are concentrated in the larger major cities of the state. Houston has the largest population of Iranians and Iranian expats, with an estimated 70,000 residents (50,000 in 1994), mainly due to the Texas Medical Center and the presence of large energy companies. Houston contains a Persian business district including shops and restaurants that has been dubbed "Little Persia" by the "Houston Press". There are many Iranian Zoroastrians and Baháʼís living there.
