Human Factors
On 45 degree in bound to left downwind for Rwy 34 at 7S5 (Independence; OR); getting close to downwind turn. I was at 1;200 feet MSL which is pattern altitude. Made radio call noting distance and intent to turn downwind. A [light aircraft] took off on Rwy 34; turned crosswind; well below pattern altitude; and then started turning downwind right underneath me; still climbing as I was about to turn downwind. I took evasive [action] and turned left to miss him. He continued into the downwind; then base/final for a full stop. I left the pattern northbound and returned back to home base.
Cessna 172 pilot reported an NMAC with another light aircraft in the pattern at 7S5 airport.
