Data sources and methodology

Every figure on Zoloth comes from a published source. This page lists those sources with their publishers and licences, and explains how we turn them into pages you can rely on.

How each figure is labelled

Next to every figure you'll see the period it covers, its source and one of these labels:

How places are matched

We identify places by their Local Government Directory (LGD) codes, the official codes of the Ministry of Panchayati Raj. When a source gives names instead of codes, we match names within the same block and district and publish only the matches we're confident about. Elections held before the current panchayat boundaries are matched to today's panchayats by name. To look up any code yourself, read how to find your gram panchayat and LGD code.

How distances and nearest facilities are worked out

Distances are straight-line distances from a reference point of the panchayat to each facility, which we calculate from published coordinates. By road it can be further. These figures are labelled "Calculated".

Block and district figures

Some data, such as health survey results, is only published for a district or block. We label it clearly so nobody mistakes it for the panchayat's own figure.

How often data is updated

Each source has its own cycle, from directory mirrors that update daily to the Census, which comes once a decade. We refresh pages when sources publish new data, and every figure shows the period it covers. Corrections our editors have verified are kept across refreshes.

What we leave out on purpose

We never import caste, religion or individual beneficiary data. Gender and education of elected heads appear only as totals for a block or district.
