As we can see, median values seem to be improving year-over-year, but unfortunately multi-entry visas are still not the default. Note that these are aggregate statistics for every consulate in the world. When applying in a specific country you want to download the latest Schengen statistics file and find the consulate with the largest percentage of multi-entry visas. I.e. for India the top consulates are as follows (I've filtered the data to consulates that issued at least 100 visas):
| Country |
Share of multi-entry visas in India |
| Germany |
95.34% |
| Greece |
91.02% |
| Switzerland |
90.90% |
| Lithuania |
87.25% |
| Austria |
87.08% |
| Belgium |
85.13% |
| Italy |
84.77% |
| Denmark |
78.51% |
| Luxembourg |
74.62% |
| Netherlands |
61.72% |
| Portugal |
59.55% |
| Czech Republic |
49.09% |
| Hungary |
48.72% |
| Estonia |
48.13% |
| Slovakia |
43.40% |
| Finland |
36.23% |
| France |
27.87% |
| Poland |
26.31% |
| Sweden |
22.14% |
| Iceland |
18.84% |
| Spain |
14.19% |
| Norway |
8.07% |
So if I were applying for a Schengen visa in India, I'd definitely aim for Germany rather than France. Though of course another caveat is that we don't know if Germany is actually issuing 6+ months Schengen visas or just allows multiple entries on visas of short duration.
