I want to know the answer to the following question:
Haredi and Chassidic communities are threatened by assimilation and intermarriage so they do not do what with non-orthodox populaions?
All the background I'm provided with is that "Nevertheless, this strategy has proved successful and the number of adherents to Orthodox Judaism, especially Haredi and Chassidic communities, has grown rapidly.". Is that enough to answer the question?
Answer: no
