一方で presents another side of a situation, often in a measured comparison of trends or characteristics.
The idea
Attach 一方で to a plain verb or い-adjective, or use な after a な-adjective and である after a noun. It can also begin a separate sentence. The two sides need a meaningful contrast, even when both numbers rise.

| い形容詞+一方で | 高い一方で |
| な形容詞+な一方で | 便利な一方で |

Watch out
増える一方だ means something keeps increasing; it does not introduce a contrasting clause. 一方で can contrast benefits and costs, not only opposite directions.
