So the Central Americans are all moving to places where the blacks don't want to live anymore?
Areas where people don't want to live have low rents which are attractive to people who don't have high income. They also go where they might find work in construction - I assume that is the reason for the concentration in Palmdale.
Since Salvadoran and Guatemalan immigration was somewhat later than Mexican immigration, they may have tended to go where there was already Spanish speakers. One reason that Central Americans may have not gone east is that many of those areas have large numbers of Asian immigrants. There are some census tracts that are generally Hispanic, with Mexicans, and Central Americans from many countries, but with Salvadorans dominant, some that are Central American dominant, usually Salvadoran dominant but, sometimes Guatemalan.
It wouldn't surprise me if some of the Guatemalan-dominant areas had significant numbers of non-Spanish speakers (or perhaps as a second language). Census Tract 1916.10 has the largest Central American to Hispanic ratio among census tracts with a Hispanic majority, and a bare Central American majority 50.3%.
1322 Guatemalan, 1207 non-Hispanic, 712 Mexican, 678 Salvadoran, 130 Nicaraguan, 114 Peruvian, and 91 Honduran.
