Methodology

01What is computed and how

One computation runs through this entire site. A jantri rate is multiplied by a declared parcel size to give a valuation base. Stamp duty is 4.9 per cent of that base and the registration fee is 1 per cent of it. Nothing else is calculated anywhere.

The two percentages are read out of the procedure dataset at build time and the build fails if the wording that carries them changes, so a revised source cannot quietly leave stale numbers on the page.

02How a band is chosen

The rate book prints a rate against a list of survey numbers. A village carries several bands at once, split by irrigation and by road situation. This record publishes every band it finds and computes the charge on all of them, so no selection is hidden.

The worked example at the top of each village record uses what is called here the principal band, which is the band the rate book applies to more survey numbers than any other in that village. It is chosen by counting the survey numbers listed against each band, then by the number of printed rate rows, then by the rate itself. It is not a mean, not a median and not a market rate. Where a village has a highway band it is usually dearer than the principal band and it is listed in full on the same page.

Across the twenty two villages this produces 472 computed bands, of which 19 villages carry an agricultural band and three carry none.

03How the three books are joined

The same village is spelled three ways across the sources, so the join is stated rather than assumed. The canonical name is the 2009 gazette spelling, because that is the legal instrument. The agricultural rate book is joined on its own uppercase printed name. The non-agricultural dataset carries its own mapping to the development authority's village list and flags six matches as spelling variants rather than exact.

Three consequences are visible on the site. Hebatpur and Sangasar sat in Barwala taluka in 2009 and the agricultural extraction covers Dhandhuka taluka, so they carry non-agricultural bands only. Sodhi has no page anywhere in either volume and carries nothing. Records from different pages of the same village are never merged or averaged, because the source gives no sub-village label to tell them apart and source page is the only discriminator.

A village named Dev Dholera in Bavla taluka is excluded by name. It is a different place.

05Limitations

Six that bear on every figure here, before the full list.

1. The valuation base is the 2011 edition of the rate book. It is not the rate a Sub-Registrar applies today, and no later revision is reflected anywhere on this site.
2. The parcel sizes are declared, not observed. Nobody buys exactly one acre or exactly a thousand square metres. Multiply through for a real parcel.
3. Stamp duty on agricultural land falls on the consideration or the market value, whichever is higher. Where a real consideration exceeds the jantri base, the duty computed here is too low.
4. The 4.9 per cent is a composite the official calculator applies. The source does not break it into duty and surcharge and states no concession for any class of buyer, so neither appears here.
5. Roughly half the procedure carries no published fee, so no total on this site is a complete cost of acquisition.
6. Neither the class of the document nor the class of the land is determined here. Both are determined at the Sub-Registrar office, and they decide which article and which base actually apply.

Beyond those, the four datasets declare 49 gaps of their own. They are published in full on what is not public, together with what would close each one.

06Corrections

A correction needs a figure, a page and a document. Anything that arrives with those three is checked against the source and either published or answered with the reason it was not. Nothing on this site is defended for being already published.
