There are no verifiable statistics regarding the survival rates of slaves from Africa to any part of the Western Hemisphere. This applies to any part of the hemisphere as well.
The nearest US Census was taken in 1830. In that year the entire United States had a population of 12.8 million, of whom 10.5 million were free white, 0.3 million free black, and 2.0 million slaves. The census recorded slaves in all states except Vermont although the numbers outside the south were very small. In the southern states the total white population was 3.1 million with 1.9 million black slaves. In two states the free white population was outnumbered by black slaves: South Carolina, 258,000 white and 315,000 black slave Louisiana, 89,000 white and 110,000 black slave. The number of slave owners was not counted by the census that year.
Some 100,000 former Black slaves became Union soldiers during the US Civil War to help the Union end the Southern rebellion They got payed less than white Union soldiers in the battle.Near the very end of the war, the South used slaves as soldiers. Prior to that, Southern slaves worked on farmlands and plantations in the South. They also served in the Confederate army as "helpers" to the army. They acted as carriers of supplies and ammunition.
The ratio was 2.64 union soldiers for every confederate soldier. NEW RESPONDENT The most optimistic calculations give as an overall ratio between the two armies, in terms of men employed on the field of 1,50-1,75 Union soldiers for every Confederate.
the sex ratio increased in the 1980s and 1990s
According to information about an 1830 census, there were 3775 free Blacks who owned slaves. In the 1860 census, there were a total of 393,975 slaveholders. In 1860, there were 3,000 free black slaveholders in the state of Louisiana, which seems to have always had the majority of black slaveholders. It is a comparison between 1830 and 1860. The US population during this time nearly tripled. The ratio of free blacks to total population remained consistent at about 10% during this time. So at a minimum, comparing 1830 to 1860, 3775 of 393,975, or 1% of slaveholders were black. Scaling the 1830 total for the increase in population, perhaps up to 3% of slaveholders were black. The ratio of slaveholders to population was roughly stable at around 1.5% during this period. In a 30-minute search, neither the total number of slaveholders in 1830 nor the total number of black slaveholders in 1860 could be located. The census documents are publicly available, so this might be a nice project to tally them up.
In 1860, approximately 25% of white households in the southern United States owned slaves. This means that not all white southerners owned slaves, but a significant portion did.
Sex ratio denotes the ratio of males to females in a population. The primary sex ratio is the ratio at the time of conception, secondary sex ratio is the ratio at time of birth, and tertiary sex ratio is the ratio of adult human beings. According to CIA estimates the current world sex ratio at birth is 107 boys to 100 girls. In 2010 the global sex ratio was 986 females to 1000 males, which got further reduced to 984 females to 1000 males in 2011.

According to the CIA World Factbook, the 2014 ratio is 1.07 boys per girl.
The answer depends on whether the ratio is in the context ofgraduate women,non-graduate men.It also depends on where in the world the numbers refer to.
