Michael Stock (born 3 December 1951) is an English songwriter, record producer and musician, best known for being a member of the songwriting and production team Stock Aitken and Waterman that achieved success in the 1980s and 1990s. He has written or produced numerous worldwide hits including 18 No. 1 records in America and the UK, and over a hundred top-40 hits. Stock is one of the most successful songwriters of all time as recognised by the Guinness Book of Records. As part of Stock Aitken and Waterman, he is acknowledged as the most successful producer-songwriter in British chart history and holds the record for the most No. 1 records with different acts, with 11.
Stock was born in Margate, Kent, England in 1951 and grew up in Swanley, Kent. He attended White Oak primary school and Swanley comprehensive school. At Swanley school he was involved in several school variety productions. He was self-taught in playing the piano and guitar and began writing songs at the age of seven. Inspired by The Beatles he soon became fixated with pop music and put together his first band at age 13, playing bass guitar and singing. Fascinated by the popular songwriting styles of Rodgers and Hammerstein, and writers such as Irving Berlin and the energy and freshness of The Beatles, he established a deep love of pop music. Stock signed a publishing contract when he was nineteen after earning a reputation as a budding songwriter, although no one had suggested a full-time career in the music world was a possibility. In 1970 Stock earned a placement at the University of Hull to study Drama and Theology and formed a band with a fellow student, the later acclaimed Oscar-winning director, Anthony Minghella. Whilst at Hull, Stock met his wife Bobbie and left university when she graduated to concentrate his efforts in making it in music. In 1975 they married and soon after, sold their house in Bury, Lancashire to move back south Stock played his first paid, solo gig at Aveley Working Men's Club in Essex in 1976, earning twenty five pounds. By the late 1970s Stock, now living in Blackheath, South London, was performing up and down the country. Performing solo, in a duo or with bands Mirage and Nightwork, Stock gained a good reputation for his live performances and was regularly booked for venues like the Hilton Hotel, Grosvenor House and the Dorchester in Mayfair. Throughout 1979 to 1981 Stock was gigging every night of the week in various bands embracing pop, dance, old standards, rock or funk. Stock's band had gone through several guitar players before he was alerted to Matt Aitken; a guitarist who had been spotted by another member of his band working on a cruise ship. Stock contacted Aitken to offer him a role in the band. Playing on cruise ships and in various bands of his own, Aitken was an accomplished guitarist whose style could adapt to any type of music. In 1982 Stock moved to Abbey Wood, South London where, along with Matt Aitken he acquired a recording desk and tape machine and formed his first record label. During the break of one of Mirage's sets on New Year's Eve 1983, Stock informed the band he would be leaving and was going into the studio to pursue his career as a songwriter and producer. Matt Aitken agreed to join him and from January 1984 onwards the pair worked exclusively in recording studios.

What was his first band called?

Indigenous peoples of Mexico (Spanish: pueblos indigenas de Mexico), Native Mexicans (Spanish: nativos mexicanos), or Mexican Native Americans (Spanish: nativo america mexicanos), are those who are part of communities that trace their roots back to populations and communities that existed in what is now Mexico prior to the arrival of Europeans. According to the National Commission for the Development of Indigenous Peoples (Comision Nacional para el Desarrollo de los Pueblos Indigenas, or CDI in Spanish) and the INEGI (official census institute), in 2015, 25,694,928 people in Mexico self-identify as being indigenous of many different ethnic groups, which constitute 21.5% of Mexico's population.
According to the National Commission for the Development of the Indigenous Peoples (CDI), there were 25,694,928 indigenous people reported in Mexico in 2015, which constitutes 21.5% of the population of Mexico. This is a significant increase from the 2010 census, in which indigenous Mexicans accounted for 14.9% of the population, and numbered 15,700,000 Most indigenous communities have a degree of financial, political autonomy under the legislation of "usos y costumbres", which allows them to regulate internal issues under customary law. The indigenous population of Mexico has in recent decades increased both in absolute numbers as-well as a percentage of the population. This is largely due to increased self-identification as indigenous, as-well as indigenous women having higher birth rates as compared to the Mexican average. Indigenous peoples are more likely to live in more rural areas, than the Mexican average, but many do reside in urban or suburban areas, particularly, in the central states of Mexico, Puebla, Tlaxcala, the Federal District and the Yucatan Peninsula. According to the CDI, the states with the greatest percentage of indigenous population are: Yucatan, with 65.40%, Quintana Roo with 44.44% and Campeche with 44.54% of the population being indigenous, most of them Maya; Oaxaca with 65.73% of the population, the most numerous groups being the Mixtec and Zapotec peoples; Chiapas has 36.15%, the majority being Tzeltal and Tzotzil Maya; Hidalgo with 36.21%, the majority being Otomi; Puebla with 35.28%, and Guerrero with 33.92%, mostly Nahua people and the states of San Luis Potosi and Veracruz both home to a population of 19% indigenous people, mostly from the Totonac, Nahua and Teenek (Huastec) groups.

How many different groups of indigenous peoples are included in those statistics?
Totonac, Nahua and Teenek (Huastec) groups.
