The primary survey is meant to analyse the social vulnerability status of the population, where sample size is defined at taluk level of the district (study area). Considering factors like physiography and population density of the study area, kindly provide suggestions on how to select the geographical location of samples (households) preferably using GIS tools (other than fishnet and random sampling tools in ArcGIS) or through other scientific or systematic methods. TIA.
1. Assign weights to different areas based on population density.
2. Identify clusters of households using GIS tools, considering factors like proximity and social or economic similarities.
3. Identify areas in proximity to essential services and facilities (e.g., healthcare, education) using GIS.
4.Develop a vulnerability index by integrating various socio-economic and environmental indicators.
5.Overlay different vulnerability layers (e.g., economic status, education levels) on GIS maps.
6.Consider accessibility factors like transportation networks.
7. Incorporate remote sensing data, such as land cover or land use maps, to identify areas with specific environmental conditions that may contribute to vulnerability.
8.Use social network analysis in GIS to identify communities with close social ties.
The sample size of this study I think you must use sample by landform units and calculate of every household have maximum people (3 or 4 people/household)
Hello Arya M. A.
Here are some strategies for selecting geographical locations of samples (households) using GIS tools and other systematic methods:
In fact, a combination of methods may be most effective. GIS tools, such as ArcGIS or QGIS, can assist in visualizing data, creating spatial layers, and analyzing patterns. Additionally, consider collaborating with experts in geography, sociology, and demography to refine your sampling strategy!

When choosing areas, for conducting a survey, start by defining the group of people you are interested in studying. Next, figure out the scope of your survey and decide how many people you want to include pick a method for selecting participants Think about organizing the data into groups if needed Select the specific locations to conduct the survey Make sure you cover all the necessary areas think about practical aspects like logistics and feasibility double-check and adjust your choices as needed, and keep detailed records of your sampling process. This ensures that your sample accurately represents the population and produces findings. Take into account factors such as how the population varies, how confident you want to be in your results, how much and how room there is for error when choosing where to conduct your survey. If there are subgroups within the population you're studying, consider using sampling. Finally,. Tweak your selected locations as required, with input from experts or stakeholders, for validation. This structured method guarantees that your survey results are both accurate and trustworthy.
Hai Arya,
Determining the geographic location of the sample size mainly depends on the sampling methods like systematic, purposive, snowball, quota, and Random etc, followed by easy access to the samples.
