Due to historical reasons and circumstances, Sephardic Bnei Anusim had not been able to return to the Jewish faith over the last five centuries, although increasing numbers have begun emerging publicly in modern times, especially over the last two decades. Except for varying degrees of putatively rudimentary Jewish customs and traditions which had been retained as family traditions among individual families, Sephardic Bnei Anusim became a fully assimilated sub-group within the Iberian-descended Christian populations of Spain, Portugal, Hispanic America and Brazil. In the last 5 to 10 years, however, "organized groups of Benei Anusim in Brazil, Colombia, Costa Rica, Chile, Ecuador, Mexico, Puerto Rico, Venezuela, Dominican Republic and in Sefarad [Iberia itself" have now been established, some of whose members have formally reverted to Judaism, leading to the emergence of Neo-Western Sephardim (see group below).
