There is a current upsurge of climate-related disasters globally with urban centres emerging as hotspots for climate risks such as floods, underlain by population growth and urbanization challenges. Yet, the literature on urban floods suggests limited estimates of “perceived vulnerability”, the latter increasingly gaining acceptance in climate change and disaster knowledge communities. Subsequently in this article, the effects of socio-demographic characteristics of households in underestimating their perceived vulnerability to flooding in Ghana is analysed, for informed flood disaster risk reduction. The findings show female headed households and those with college education as relatively more likely to underestimate their vulnerability to floods, compared to male headed households and those with no education, respectively. The age of male household heads determined their underestimation of floods yet the relatiowas non-linear. Additionally, the perceived vulnerability of a household to floods and ability to estimate its status depends on the sex of household head, to potentially influence decision-making and choice of adaptation. In conclusion, differences in the effects of households' background characteristics on perceived vulnerability and capacity to estimate the outcome suggest context specific measures or social interventions in addressing attitudes towards floods disaster risk, and subsequently in formulating disaster risk reduction strategies and policy interventions.

当前，全球范围内与气候有关的灾害激增，城市中心逐渐成为诸如洪水之类的气候风险的热点地区，而人口增长和城市化挑战则是其基础。然而，有关城市洪水的文献表明，对“可感知的脆弱性”的估计有限，后者在气候变化和灾难知识界越来越受到认可。随后，在本文中，分析了家庭的社会人口统计学特征在低估了他们认为加纳遭受洪灾的脆弱性方面的影响，以期在知情的情况下减少洪灾风险。调查结果显示，与以女性为户主的家庭和没有受过教育的家庭相比，以女性为户主的家庭和受过大学教育的家庭分别更有可能低估了其易受洪灾的影响。男性户主的年龄决定了他们对洪灾的低估，但相关系数是非线性的。另外，一个家庭对洪水的脆弱性和估计其状况的能力取决于户主的性别，从而有可能影响决策和适应选择。总之，家庭背景特征对感知脆弱性和估计结果能力的影响存在差异，这表明在处理对洪灾灾害风险的态度，随后制定减少灾害风险战略和政策干预措施时，应采用针对具体情况的措施或社会干预措施。一个家庭对洪水的脆弱性和估计其状况的能力取决于户主的性别，从而可能影响决策和适应选择。总之，家庭背景特征对感知脆弱性和估计结果能力的影响存在差异，这表明在处理对洪灾灾害风险的态度，随后制定减少灾害风险战略和政策干预措施时，应采用针对具体情况的措施或社会干预措施。一个家庭对洪水的脆弱性和估计其状况的能力取决于户主的性别，从而可能影响决策和适应选择。总之，家庭背景特征对感知脆弱性和估计结果能力的影响存在差异，这表明在处理对洪灾灾害风险的态度，随后制定减少灾害风险战略和政策干预措施时，应采用针对具体情况的措施或社会干预措施。
