I created isochrones using Iso-Area as polygons algorithm is QGIS. I would like to calculate the proportion of the population covered by the created isochrones. Is there any tool in QGIS to do this?

1Depends on the population data you've got.– ErikCommented Feb 4, 2021 at 11:02

Use zonal statistics, see e.g. here for a similar problem (population as raster layer, overlay with a polygon): gis.stackexchange.com/a/382557/88814– BabelCommented Feb 4, 2021 at 11:25

@Erik I have not collected the data yet. which type of population data do I need for this analysis?– ElhamCommented Feb 5, 2021 at 9:30

I'd go with Pop-density, then you can intersect and calculate the approx. pop based on the area of the intersections.– ErikCommented Feb 5, 2021 at 9:56
