However, when I downloaded the EXCEL files listed at the foot of that Web page, there are no Names etc, so that it is probably only of statistical interest rather than genealogical.
As Carolyn has indicated, Scotland's People does have available on-line, the BMDs extracted from the low proportion of OPRs (Old Parish Registers) handed over mainly by Church of Scotland churches on the extablishment of the GRoS in 1855; supplemented more recently by some Catholic OPRs.
SP has more information on those aspects.
For your initial searches for pre-1855 (GRoS established) BMD Records, you may also find the LDS Family Search site of use - BUT always attemting to confiirm on SP-
The present LDS FS Site takes some time to become accustomed to; but it certainly can be extremely helpful.
