In addition, the socio-demographic ratios among the participants, the age distributions of the participants, and the dates of the year in our survey were similar to those same features in the 2008 survey [ 12].
Although there is still some variation between and within countries, at the regional level two major changes have taken place: a reduction in demographic dependency (ratio of people younger than 14 or older than 65 to the working-age population) and population aging (ECLAC 2007).
This phenomenon has been suggested by De Benedictis and Franceschi [ 37] from the observation that the demographic males/females ratio among centenarians is consistently different depending on the geographic origin of individuals.
Table 4 shows the proportions of those achieving a TES by demographic variable, with ratios of observed to expected proportions.
While synonymous diversity levels are indicative of recent selection and demographic events, dN/dS ratios are more reflective of long-term evolutionary history [ 53].
The tendency towards increased crude and demographic adjusted hazard ratios observed with antimetabolite therapy (see tables 3 and 4) corresponded to greater use of these drugs in patients who had systemic inflammatory co-morbidities and were older.
Instead of high fertility rates, demographers study ageing, dependency ratios, the "demographic dividend" (a bulge of working-age adults) and distorted sex ratios, which result when millions of parents choose the sex of their children, often by aborting baby daughters.The result, suggests Mr May, is that demography is more complex, if less dramatic, than it used to be.
We propose an analytical approximation to the wave-speeds of IDE solutions with periodic landscapes of alternating good and bad patches, where the dispersal scale is greater than the extent of each good patch and where the ratio of the demographic rates in the good and bad patches is given by a small parameter, denoted as ε.
So, in divesting itself of just 1.5 percent of the land, Israel significantly recalibrated the so-called "demographic equation" (the ratio of Jews to Arabs in the area under its control).
They have confirmed Andrews and Harris's (1964) demographic findings (sex ratio and the high rate of spontaneous recovery).
