Dialectal Variation
British vs American Usage
Differences
Usage is remarkably consistent between BrE and AmE in meaning and frequency. Slight preference for 'essential' or 'key' in less formal American contexts where BrE might still use 'integral'.
Connotations
Both varieties carry a formal, precise connotation. In BrE, it may be slightly more common in institutional or traditional contexts (e.g., 'integral to the fabric of society').
Frequency
Equally frequent in academic and technical writing in both dialects. Slightly higher frequency in BrE in general journalism and descriptive prose.

- Overusing in informal contexts where 'essential' or 'key' would suffice.
