Question

where do I put a coma while they provided a supportive community that allowed immigrants to maintain their cultural traditions and access familiar goods and services they were often located in overcrowded and unhealthy areas that reflected the socioeconomic challenges facing new arrivals

Answer 1

To improve the clarity and readability of your sentence, you can add a few commas. Here’s a revised version:

"While they provided a supportive community that allowed immigrants to maintain their cultural traditions and access familiar goods and services, they were often located in overcrowded and unhealthy areas that reflected the socioeconomic challenges facing new arrivals."

In this sentence, a comma is added before "they were often located" to separate the two independent clauses.
