Abstract
This study aims to examine the regional characteristics that affect the region’s level of collective donation behavior. Most studies examining factors affecting donation behavior were conducted at the individual level. However, regional-level comparative studies enable an understanding of environmental factors influencing donation behavior. Especially in this study, the number of nonprofit fundraising organizations per unit population in each region was included to observe how much the activities of related organizations affect the regional donation rate and average donation amount. The number of fundraising organizations did not have a significant relationship with the donation rate of the region but had a limited positive effect on the average donation amount of donors. In addition, the regional economic level also significantly impacted the regional donation level. It was found that the ratio of poor households or major demographic characteristics had different effects on the donation rate and the average donation amount, respectively.
