Dear Serigne Mbacké Coly the data required for socio-economic vulnerability depends on the scope of the intended study. Also, the availability of the required data from National Institutes depends on the nation. If you clarify, you could get some direct assistance and answers.

Thank you Dear Emmanuel Eze ,

The scope of my study is to determine different socio-economic groups (e.g. "less vulnerable", "vulnerable" and "very vulnerable") in relation to climate change. To do this, I need biophysical data (already available) and socio-economic data. So the question asked here is to establish a list of data and to see if they are available in order to get them from the national statistical institute. I hope this helps!

Alright Serigne Mbacké Coly

Have you read this paper on "Future drought risk in Africa: Integrating vulnerability, climate change, and population growth" by Ahmadalipour, et al. (2019)?

This provides a lot of details related to your question and more. Also, the World Bank, OECD and other institutions freely and regularly provide socio-economic data on their website but these are on a national scale.

Thank you very much Emmanuel Eze,

I had not yet read this article but I am sure it will be of great importance to me. I have already sent a request for it to the author.

For data from institutions (usually online), as you said, they are at the national level and my study focuses more on the household level mainly rural households.

There are a lot of studies that have done vulnerability assessment of households livelihood to climate change. You can read Hahn et al. 2009 and many moreArticle The Livelihood Vulnerability Index: A pragmatic approach to ...

Two examples of data collection and analysis for determining vulnerability:

2. https://doi.org/10.1061/(ASCE)NH.1527-6996.0000290

Vulnerability, though, always must be viewed as a process:

Thank you Ilan Kelman for these resources which will be of great help to me.

For socio-economic vulnerability study, data particularly education level i.e illiteracy level, poverty and level of unemployment in the nation or state need to be searched

First, it depends on your definition of vulnerability. We use IPCC's, vulnerability=sensitivity+exposition-adaptive capacity. For example Covid19 and flooding we used the following. I hope this is useful for you.

Sensitivity: % of people with the age of greatest contagion (35-39 years) Number of positive cases of COVID-19 Death rate from chronic diseases that establish health preconditions in the population Percentage of no streets or access to housing Percentage of overcrowded households % of dwellings without drinking water % of dwellings without exclusive bathroom % of dwellings without exclusive shower % of homes without garbage collection service Population Density Age dependency ratio Diabetes mortality rate Heart Disease Mortality Rate Lung Disease Mortality Rate Mortality rate of cancer diseases Mortality rate from HIV diseases

Exposition:

% of households with members who work outside the city % of people working in frontline exposure activities Rate of commercial establishments or concentration points Agglomeration alert rate

Adaptive Capacity:

Average level of education of people aged 24 or over % of people who have social or private insurance Level of distancing to health units and centers % of people with access to technology Level of organization of the sector (neighborhood leaders)

Level of distancing to firefighter headquarters

Level of distancing to police offices

While vulnerability is parameterized following what M.P. Cornejo-Rodriguez described very well, the way the three dimensions (exposure, sensitivity, and adaptive capacity) are evaluated is quite subjective and very much context-based. This is true, especially for the adaptive capacity dimension. The World Bank undertakes annual rural socioeconomic surveys in many countries and the questionnaires they use (e.g., https://microdata.worldbank.org/index.php/catalog/3823/related-materials) may be helpful for you to design yours.

Thank you dear Mosisa
