Katy was once a major sugar cane producer and rice producer. It has a festival the second weekend in October to honor and recoginize the former rice producing town.

Katy is home to the Igloo Corporation, an internationally-known manufacturer of cooling and portable refrigeration products. Igloo Corporation consolidated all of their operations in Katy in 2003. For more information visit the Katy community website.

History
Katy residents often split the city into two informal sections: "Old Katy" (or Katy Proper) and "Katy Area". Old Katy is the actual city limits of Katy and lies mostly north of Interstate 10. This is the original Katy from before the 1970s when Houston's Energy Corridor (and the development that came with it) made its way west on I-10.

The "Katy area" is made up of large sections of unincorporated Harris and Fort Bend counties and mostly sits east and southeast of the city limits of Katy. This area is within the Katy Independent School District and nearly everyone in this area has a Katy postal address.

The Katy area includes new upscale developments and master planned communities such as Cinco Ranch, Wood Creek Reserve, Grayson Lakes, Seven Meadows, Firethorne and Grand Lakes, while also encompassing developments from the 1970s and 1980s such as Memorial Parkway, Kelliwood and Nottingham Country.

All of the "Katy area" lies in the city of Houston's extraterritorial jurisdiction (ETJ), not Katy's ETJ. This means that the areas of "Katy area" are controlled by the city of Houston and the city has the ability to annex it in the future. The city of Katy cannot annex this area unless the city of Houston releases the area's ETJ to Katy, which has occurred in several small chunks in recent years. The most recent instance of this was in 2001 when Houston ceded about 400 acres (1.6 km²) of ETJ to the City of Katy to allow the Katy Mills Mall and surrounding parking lot to be built entirely within the City of Katy.

As of the census of 2000, there were 11,775 people in "Old Katy", 3,888 households, and 3,083 families residing in the city. The population density was 1,103.7 people per square mile (426.1/km²).

Economy
Houston's energy industry is recognized worldwide—particularly for oil—and biomedical research, aeronautics, and the ship channel are also large parts of its economic base. The area is a leading center for building oilfield equipment. Much of Houston's success as a petrochemical complex is due to its busy man-made ship channel, the Port of Houston. The port ranks first in the United States in international commerce, and is the tenth-largest port in the world. Unlike most places, where high oil and gasoline prices are seen as harmful to the economy, they are generally seen as beneficial for Houston as many are employed in the energy industry.

The Houston–Sugar Land–Baytown MSA's Gross Area Product (GAP) in 2006 was $325.5 billion, slightly larger than Austria’s, Poland’s or Saudi Arabia’s Gross Domestic Product (GDP). When comparing Houston's economy to a national economy, only 21 countries other than the United States have a gross domestic product exceeding Houston's regional gross area product. Mining, which in Houston is almost entirely exploration and production of oil and gas, accounts for 11% of Houston's GAP; this is down from 21% in 1985. The reduced role of oil and gas in Houston's GAP reflects the rapid growth of other sectors, such as engineering services, health services, and manufacturing.

Houston ranks second in employment growth rate and fourth in nominal employment growth among the 10 most populous metro areas in the U.S. In 2006, the Houston metropolitan area ranked first in Texas and third in the U.S. within the category of "Best Places for Business and Careers" by Forbes magazine. Forty foreign governments maintain trade and commercial offices here and the city has 23 active foreign chambers of commerce and trade associations. Twenty foreign banks representing 10 nations operate in Houston, providing financial assistance to the international community.

Attractions
Houston is a multicultural city with a large and growing international community. The Houston MSA is home to an estimated 1.1 million (21.4 percent) residents that were born outside the United States, with nearly two-thirds of the Houston MSA foreign-born population are from south of the US-Mexico border. More than one in five foreign born Houstonians are from Asia. The city is home to the nation’s third largest concentration of consular offices representing 86 nations. Houston is designated as a gamma world city by the Globalization and World Cities Study Group and Network. Houston received the official nickname of "Space City" in 1967 because it is home to NASA's Lyndon B. Johnson Space Center. Other nicknames include "H-Town," "Screwston," "The Big Heart," "Bayou City," "Clutch City," "Hustletown," and "Magnolia City." The city is home to Lakewood Church, the largest church in America with over 50,000 members attending each week.

Houston has an active visual and performing arts scene. The Theater District is located downtown and is home to nine major performing arts organizations and six performance halls. It is the second largest concentration of theater seats in a downtown area in the United States. Houston is one of only five United States cities with permanent, professional, resident companies in all major performing arts disciplines: opera (Houston Grand Opera), ballet (Houston Ballet), music (Houston Symphony Orchestra), and theater (The Alley Theatre). Houston is also home to many local folk artists, art groups and various smaller progressive arts organizations. Houston attracts many touring Broadway acts, concerts, shows, and exhibitions for a variety of interests.

Houston is home to the Bayou City Art Festival, which is considered to be one of the top five art festivals in the United States.

The Museum District is home to many popular cultural institutions and exhibits, attracting more than 7 million visitors a year. Notable facilities located in the district include The Museum of Fine Arts, Houston Museum of Natural Science, the Contemporary Arts Museum Houston, Holocaust Museum Houston, and the Houston Zoo. Located in the nearby Montrose area are The Menil Collection and Rothko Chapel.

Many venues scattered across Houston regularly host local and touring rock, blues, country, hip hop and Tejano musical acts. Unfortunately, there has never been a widely renowned music scene in Houston. Artists seem to relocate to other parts of the United States once attaining some level of success. A notable exception to the rule is Houston hip-hop, which celebrates the unique southern flavor and attitude of its roots. This has given rise to a strong, independent hip-hop music scene, influencing and influenced by the larger Southern hip hop and gangsta rap communities. Many Houstonian hip-hop artists have attained commercial success.

Many annual events celebrate the diverse cultures of Houston. The largest and longest running is the annual Houston Livestock Show and Rodeo, held over 20 days from late February to early March. Another large celebration is the annual night-time Houston Pride Parade, held at the end of June. Other annual events include the Houston Greek Festival, Art Car Parade, the Houston Auto Show and the Houston International Festival.Space Center Houston is the official visitors’ center of NASA's Lyndon B. Johnson Space Center. Here one will find many interactive exhibits including moon rocks, a shuttle simulator, and presentations about the history of NASA's manned space flight program.

The Theater District is a 17-block area in the center of downtown Houston that is home to the Bayou Place entertainment complex, restaurants, movies, plazas, and parks. Bayou Place is a large multilevel building containing full-service restaurants, bars, live music, billiards, and art house films. The Houston Verizon Wireless Theater stages live concerts, stage plays, and stand-up comedy; and the Angelika Film Center presents the latest in art and foreign and independent films.

Houston is home to many parks including Hermann Park, which houses the Houston Zoo and the Houston Museum of Natural Science, Lake Houston Park, Memorial Park, Tranquility Park, Sesquicentennial Park and Sam Houston Park which contains restored and reconstructed homes which were originally built between 1823 and 1905). The city has 337 city parks and over 200 green spaces—totaling over 19,600 acres (79 km²) that are managed by the city—including the Houston Arboretum and Nature Center. The Houston Civic Center was replaced by the George R. Brown Convention Center—one of the nation's largest—and the Jesse H. Jones Hall for the Performing Arts, home of the Houston Symphony Orchestra and Society for the Performing Arts. The Sam Houston Coliseum and Music Hall have been replaced by the Hobby Center for the Performing Arts.
