What is Swift's satirical method in "A Modest Proposal" and how does it address the his satirical message?

Swift's famous essay takes a contemporary issue--the Irish
Famine--and the British government's response to it and then satirises the situation in
his treatise by assuming the voice of a statistical planner. You might want to think
about the number of times that statistics are referenced. Consider the following
example:

I
have reckoned upon a medium, that a child just born will weigh twelve pounds, and in a
solar year if tolerably nursed increaseth to twenty-eight
pounds.

Note how Swift makes
every effort to present himself as a reasonable, logical man who has thought through his
sums with great care, even trying to establish a "medium" of a baby's birth weight. We
need to be aware of the wider implications of what Swift is satirising. He is not just
trying to satirise the response of the British government--he is also protesting against
a view of humanity where humans are treated as numbers and mothers to "breeders" and
babies to a food source. Swift's satirical method is to make himself appear as the most
chilling, cold-blooded monster possible so as to reveal similar attitudes in his
audience.
