two thirds fouls toa family, in that ftate---exclufive of In- 
dians and Negroes—The proportion to a houfe is 6 23.3 
For, the famzlies are to the houfes, in that ftate, as fix to 
five. In Bofton, there are to a family, 532, fouls: and 
in the three next largeft towns, placed in the order of 
their magnitude, the proportions of perfons to a family, 
areas follow, viz.Salem, 53,0. , Marblehead, Sco Newbu-

ry-Port, 4°: At Ipfwich, containing four thoufand five 
hundred and fixty two inhabitants (and. which. will be 
mentioned hereafter,) the proportion. is, 5,°... In. this 
eflimate for Maffaclfufetts, the diftriG of Maine is not in- 
cluded: but the ftate contains 373.324 inhabitants, exclu- 
five of that diftri&.—When the cenfus in completed, for 
the feveral ftates in the Union, the refult it will furnith, 
on this fubje@, will prove highly interefting—It appears,. 
however, by the cenfus for the large and populous flate 
of Maffachufetts, that the proportion of births to. marria~ 
ges, there, greatly exceeds that which obtains in fome of 
the principal countries of Europe: And, it is probable, 
the refult will be found nearly the fame, in this  particu- 
lar, with relation to the major part of the Union. 
‘There is, however, another means, by which the -fu— 
perior number of births in proportion tothe whole number 
living, in this country,---compared with the proportion 
which obtains, in this refpe&, in profperous European 
countries,—may be afcertained.—In an eflay for afcertain— 
ing the population of France, by Meffrs. Du Sejour, the 
Marquis De Condorcet and De La Place, (in the memoirs 
of the Royal Academy of {ciences for 17343,) it is aflumed 
as an hypothefis---that multiplying the medium of annu- 
al births in the whole kingdom, by 252, will give the 
number of inhabitants; and that, for the cities of Paris 
and Verfailes, thirty muft be the multiplier, The Count 
De Buffon fuppofes, that the number of thofe who die in. 
France, annually, is “, ofall the living; and, confe-
