Perception of Generation Z, Y, X, and Baby Boomers on Expansion of Lawn Uses in South Korea

Background and objective: Expanding the use of lawns is necessary for environmental improvement and climate change mitigation. This study analyzed public perceptions of expanding lawn uses with different generations. Methods: We divided the respondents into Generation Z, Generation Y (Millennials), Generation X (Xers), and Baby Boomers, and analyzed the experiences and preferences of lawn uses, and the perception of the need for lawn planting or installation (hereinafter referred to as “lawn P/I”) in major locations and expanding lawn uses. A survey was conducted online from May to June 2024 nationwide. The survey had a total of 1,012 respondents, including 189 from Generation Z, 288 from Generation Y, 309 from Generation X, and 226 from the Baby Boomers. The collected data were statistically analyzed using chi-square test, multiple regression analysis, etc. Results: For the frequency of places where lawns were experienced and the amount of time spent on lawns, statistically significant differences were found among generations. Preferred activities on lawns did not differ. There was no differencebetween generations in the perception of the need for lawn P/I in places such as parks, idle land, and reserved land, but there was a difference between generations in places such as school playgrounds, artificial grounds, and pet parks. Generation Z had a statistically significantly lower perception of the need to expand the use of lawns for eco-friendly living environment management. Compared to Baby Boomers, Generation Z also had a statistically significantly lower perceptionof the need for policies to expand green spaces with lawns, and the need for national institute-led research. There was no statistically significant difference between generations in the perception of the need for policies to revitalize the lawnindustry, but Generation Z's interest in or expectations for jobs related to the lawn industry seemed to be low. Conclusion: Lawn use experiences and preferences, as well as perceptions of the need for lawns, need to be considered by generations. Generations Z and Y have limited experience with lawns and perceive the need for lawn P/I as low, withGeneration Z showing a significant difference in particular. Baby Boomers have a positive attitude toward lawns as a part of nature. Generation X and Baby Boomers have a high level of perception of the need for policies and research to expandlawn use, and showed a positive attitude toward lawn industrialization and job creation. The public relations of policies and research to expand lawn use toward Generations Z and Y will be necessary.
