The COVID-19 pandemic triggered social and economic stagnation worldwide, significantly impacting people's lives. In addition, the Russia-Ukraine war that began in 2022 resulted in rising food prices globally, severely affecting low- and middle-income countries. This study aimed to examine the impact of these unprecedented crises on individual values, focusing on Senegal's urban population. This study is the first to quantitatively assess changes in the values of urban Senegalese during this global crisis. Surveys were conducted in Saint-Louis, Senegal, in August-September 2018 and June-July 2022. The timing of these studies coincides with the onset of the COVID-19 pandemic in early 2020 and the outbreak of the Russia-Ukraine war in February 2022. The findings revealed a 19.9% decrease in the average monthly cost of living per capita between 2018 and 2022, attributed to the combined effects of rising food prices and unemployment. Furthermore, the proportion of households spending less than $3.50 per person per day-below the lower-middle-income class poverty line-increased by 11.05%. Our analysis indicates a decline in values such as benevolence, universalism, hedonism, and self-direction. In contrast, values related to power and achievement significantly increased following the pandemic. These results suggest that individual values are flexible and may change in response to external factors such as global crises.
新冠疫情在全球引发了社会和经济停滞,对人们的生活产生了重大影响。此外,2022年爆发的俄乌战争导致全球食品价格上涨,严重影响了低收入和中等收入国家。本研究旨在考察这些前所未有的危机对个人价值观的影响,重点关注塞内加尔的城市人口。本研究首次对全球危机期间塞内加尔城市居民的价值观变化进行了定量评估。研究分别于2018年8月至9月以及2022年6月至7月在塞内加尔的圣路易进行。这些研究的时间与2020年初新冠疫情的爆发以及2022年2月俄乌战争的爆发相吻合。研究结果显示,由于食品价格上涨和失业的综合影响,2018年至2022年期间人均每月生活成本平均下降了19.9%。此外,每天人均支出低于3.50美元(低于中低收入阶层贫困线)的家庭比例增加了11.05%。我们的分析表明,仁爱、普遍主义、享乐主义和自我导向等价值观有所下降。相比之下,与权力和成就相关的价值观在疫情之后显著增加。这些结果表明,个人价值观具有灵活性,可能会因全球危机等外部因素而发生变化。
