"Poverty-stricken persons" is a common way to describe those living in extreme poverty. However, using the same term repeatedly can make one's writing seem repetitive. Instead, one could use synonyms such as "impoverished individuals," "destitute people," or "indigent families." Other options include "penniless citizens," "underprivileged beings," and "disadvantaged populations." Alternatively, one could also use descriptive phrases like "those living in extreme destitution," "people facing severe economic hardship," or "individuals suffering from poverty." Whatever synonym or phrase used, it's important to remain respectful and empathetic towards those living in poverty and avoid using derogatory language.
