To determine various insights from the given data, we will follow a structured step-by-step process:
1. Calculate Total Population:
The total population will be the sum of all age groups provided in the table.
[tex]\[
\text{Total Population} = 74,181,467 + 30,672,088 + 82,134,554 + 81,489,445 + 40,267,984
\][/tex]
Adding these numbers together:
[tex]\[
\text{Total Population} = 308,745,538
\][/tex]
2. Portion of the Population Under 18:
To find the portion of the population that is under 18, we will divide the number of individuals under 18 by the total population.
[tex]\[
\text{Portion Under 18} = \frac{\text{Population Under 18}}{\text{Total Population}}
\][/tex]
Substituting the values:
[tex]\[
\text{Portion Under 18} = \frac{74,181,467}{308,745,538} \approx 0.240267
\][/tex]
Thus, the portion of the US population under the age of 18 in 2010 is approximately 0.240267, or 24.03%.
3. Identify the Largest Segment of the Population:
To find the largest segment of the population, we will compare the totals for each age group given in the table. The numbers are as follows:
- Under 18: 74,181,467
- 18-24: 30,672,088
- 25-44: 82,134,554
- 45-64: 81,489,445
- 65 and older: 40,267,984
The largest number among these is 82,134,554, which corresponds to the age group 25-44.
Therefore, the largest segment of the population in 2010 was the 25-44 age group.
4. Illustrating Trends:
The table illustrates how the US population in 2010 is distributed across different age groups. Specifically, it shows:
- Which age group has the largest segment (25-44).
- The relative sizes of each age group, indicating trends in demographics, such as a large young population under 18 and significant numbers in the working age groups (25-44 and 45-64).
To summarize:
- The portion of the US population under the age of 18 in 2010 was approximately [tex]\(0.240267\)[/tex] (or roughly 24.03% of the population).
- The largest segment of the population in 2010 was the age group 25-44, with 82,134,554 people.
- The table helps illustrate the age distribution of the US population in 2010, indicating demographic trends such as the size of the workforce and the potential future changes in aging.
