Could someone rephrase this entire sentence for me.

Mexican-Americans are Americans of Mexican descent. After the annexation of parts of Mexico in 1848, about 30,000 individuals now lived in the U.S. and became full U.S. citizens. Large-scale new migration augmented their numbers during the 1910s, as Mexico was torn by a high-casualty civil war. Until the 1960s, most lived within a few hundred miles of the border, although some resettled along frail lines from the Southwest to the Midwest. More recently, Mexican Americans have diffused throughout the U.S., especially in the Midwest and Southeast, with the largest numbers in California and Texas. They remain concentrated in low-wage jobs in agriculture, hotels and restaurants, construction, landscaping, and meat packing. Mexican-American identity has also changed markedly throughout these years. In the past hundred years Mexican-Americans have campaigned for voting rights, stood against educational, employment, and ethnic discrimination and stood for economic and social advancement. At the same time many Mexican-Americans have struggled with defining and maintaining their community's identity. In the 1960s and 1970s, some Hispanic student groups flirted with nationalism and differences over the proper name for members of the community of Chicano/Chicana, Latino/Latina, Mexican-Americans, Hispanics or simply La Raza became tied up with deeper disagreements over whether to integrate into or remain separate from Anglo society, as well as divisions between those Mexican-Americans whose families had lived in the United States for two or more generations and more recent immigrants.

No one will do your work for you, but if you'll read several of these search results and try your hand at paraphrasing that PARAGRAPH (it's definitely not a sentence!), someone here will be happy to check it for you.

Americans of Mexican descent are known as Mexican-Americans. After parts of Mexico were annexed in 1848, around 30,000 individuals became U.S. citizens and settled in the U.S. Their numbers increased during the 1910s due to a civil war in Mexico. Until the 1960s, most Mexican-Americans lived within a few hundred miles of the border, but some migrated to the Midwest from the Southwest. Currently, Mexican Americans are spread throughout the U.S., with significant populations in California and Texas. Many work in low-wage jobs such as agriculture, hotels and restaurants, construction, landscaping, and meatpacking. Mexican-American identity has evolved over time, with campaigns for voting rights and against discrimination, as well as efforts for economic and social progress. However, defining and maintaining their community's identity has been a challenge. In the 1960s and 1970s, Hispanic student groups had debates over terms like Chicano/Chicana, Latino/Latina, Mexican-Americans, Hispanics, or simply La Raza. These discussions were tied to deeper disagreements about integration into Anglo society and divisions between long-established Mexican-American families and more recent immigrants.
