Variant notes

と共に — The kanji spelling leans literary/written — announcements, narration, and formal writing; plain とともに is fine everywhere including speech.

Notes

Unlike casual 一緒いっしょに, which needs the same subject sharing one action, とともに also covers the "as N, so does the other" reading with two entirely different subjects — 一緒に replaces neither usage cleanly.

につれて
Both can render "as X, so does Y," but につれて strictly requires a GRADUAL, causally-linked proportional change and can never mean mere accompaniment, while とともに also covers plain co-occurrence — even a static accompaniment counts (家族とともに暮らす has no change at all), which につれて cannot express.
