In 2023, people from 30 to 39 years of age made up the largest age group in Sweden. There were nearly 1.5 million people who belonged to this age group. People aged 50 to 59 years made up the second largest age group in Sweden, followed by people between 40 and 49 years. Moreover, there were nearly 1.2 million children between zero and nine, and 3,000 people aged 100 years or more.

Increasing population

Since 2000, the Swedish population increased steadily. This is mainly explained by the country's positive migration flow, but also that more people are being born than people dying.

Decreasing fertility rate

Even though the Swedish population increased steadily during this century, the country's fertility rate decreased steadily since 2010. In 2023, the number of babies born reached a record low. In Europe, however, Sweden's fertility rate is higher than the average.

The dataset contains the statistical indicators relating to the characteristics of families and couples calculated on the basis of 2011, 2001 and 1991 Census data. The indicators are calculated at three levels of detail: municipality of Milan; 9 municipalities; 69 NIL with higher population to the 3,000 inhabitants. For a limited number of indicators, the 1991 data are not available and the 2001 data are disseminated only at the municipal level. The indicators are defined as follows: * 1) Average number of members per family (ratio between the total number of residents in the family and the number of families); * 2) Families with only one member every 100 families (Percentage ratio between the number of one-member families and the total number of families); * 3) Families with 5 or more members every 100 families (Percentage ratio between the number of families with 5 or more members and the total number of families); * 4) Young couples with children for every 100 young couples (Percentage ratio between the number of young couples with children and the total number of young couples; both members of the couple less than 35 years old); * 5) Young people living alone for every 100 young people (Percentage ratio between the number of one-person households, without cohabitants, made up of a person aged 15-34 and the total population aged 15-34); * 6) Population over 65 years old living alone every 100 over 65 years old (Percentage ratio between the number of one-person households, without cohabitants, made up of a person aged 65+ and the population aged 65+); * 7) Mixed couples every 100 couples (Percentage ratio between the number of couples with a foreign and an Italian component and the total number of couples); * 8) Unmarried couples every 100 couples (Percentage ratio between the number of unmarried couples and the total number of couples); * 9) Single-parent households for every 100 households with children (Percentage ratio between the number of single-parent households and the total number of households with children).

Block Groups (BGs) are statistical divisions of census tracts, are generally defined to contain between 600 and 3,000 people, and are used to present data and control block numbering. A block group consists of clusters of blocks within the same census tract that have the same first digit of their four-digit census block number.This map is necessary for the CDBG team within DCA.About Poverty Data from the American Community Survey explained by SocialExplorer:Poverty statistics in American Community Survey products adhere to the standards specified by the Office of Management and Budget in Statistical Policy Directive 14. The Census Bureau uses a set of dollar value thresholds that vary by family size and composition to determine who is in poverty. Further, poverty thresholds for people living alone or with nonrelatives (unrelated individuals) vary by age (under 65 years or 65 years and older). The poverty thresholds for two-person families also vary by the age of the householder. If a family's total income is less than the dollar value of the appropriate threshold, then that family and every individual in it are considered to be in poverty. Similarly, if an unrelated individual's total income is less than the appropriate threshold, then that individual is considered to be in poverty.In determining the poverty status of families and unrelated individuals, the Census Bureau uses thresholds (income cutoffs) arranged in a two-dimensional matrix. The matrix consists of family size (from one person to nine or more people) cross-classified by presence and number of family members under 18 years old (from no children present to eight or more children present). Unrelated individuals and two-person families are further differentiated by age of reference person (householder) (under 65 years old and 65 years old and over).

To determine a person's poverty status, one compares the person's total family income in the last 12 months with the poverty threshold appropriate for that person's family size and composition (see example below). If the total income of that person's family is less than the threshold appropriate for that family, then the person is considered "below the poverty level," together with every member of his or her family. If a person is not living with anyone related by birth, marriage, or adoption, then the person's own income is compared with his or her poverty threshold. The total number of people below the poverty level is the sum of people in families and the number of unrelated individuals with incomes in the last 12 months below the poverty threshold.

Since ACS is a continuous survey, people respond throughout the year. Because the income questions specify a period covering the last 12 months, the appropriate poverty thresholds are determined by multiplying the base-year poverty thresholds (1982) by the average of the monthly inflation factors for the 12 months preceding the data collection. See the table in Appendix A titled "Poverty Thresholds in 1982, by Size of Family and Number of Related Children Under 18 Years (Dollars)," for appropriate base thresholds. See the table "The 2012 Poverty Factors" in Appendix A for the appropriate adjustment based on interview month.

For example, consider a family of three with one child under 18 years of age, interviewed in July 2013 and reporting a total family income of $14,000 for the last 12 months (July 2012 to June 2013). The base year (1982) threshold for such a family is $7,765, while the average of the 12 inflation factors is 2.35795. Multiplying $7,765 by 2.35795 determines the appropriate poverty threshold for this family type, which is $18,309. Comparing the family's income of $14,000 with the poverty threshold shows that the family and all people in the family are considered to have been in poverty. The only difference for determining poverty status for unrelated individuals is that the person's individual total income is compared with the threshold rather than the family's income.Poverty status was determined for all people except institutionalized people, people in military group quarters, people in college dormitories, and unrelated individuals under 15 years old. These groups were excluded from the numerator and denominator when calculating poverty rates.
