It is no secret that Boston is booming, prompting long-term initiatives from City administration to address growing housing needs and expanding available resources. A report released last week illustrates some of the demographic changes in the city, and populous Dorchester tops most of the lists by raw numbers alone.

The Boston Redevelopment Authority’s 2015 report on Boston by the Numbers pulls from census data, neighborhood surveys, and BRA research to analyze the spread of Boston’s some 656,000 residents, over 120,500 of them in Dorchester.

Since 2010, Boston’s foreign-born population grew by more than 19 percent, settling at 177,461 foreign born residents by 2014. They accounted for 27.1 percent of the city, according to the report.

Haitian residents make up 7.6 percent of the city’s foreign-born residents, the third most populous demographic.

Dorchester, with 38,683 foreign born residents, ranks fourth in the city by percentage (32 percent). Mattapan’s 8,701 foreign-born residents place it at number two (35.9 percent). Standing apart from the rest, East Boston’s population is 50.5 percent foreign born.

Certain populations overlap, according to the report. Of the elderly, 35.7 are foreign-born, with 35.5 percent of the elderly speaking a language other than English at home.

And the city is aging, with the elderly population up 9 percent from 2010 and currently sitting at 67,857 residents over 65 across Boston. Dorchester has an elderly population of 10,882; nearly twice that of the second highest overall number of 5,492 in West Roxbury, also with the highest elderly proportion overall at 17.8 percent of their population. However, Dorchester is the fourth lowest by percentage (9 percent) of elderly residents.

The number of families with children are declining across the city from 44.4 percent in 2014 to 42.4 percent of family households in 2014. Families headed by women with no husband present make up 35.5 percent of all family households, and those female-headed households make up 64.3 percent of all families in poverty in Boston.

Despite the overall trend, Dorchester remains one of the neighborhoods with disproportionately high child populations. Along with Roxbury, Hyde Park, Mattapan, Roslindale, and East Boston, it is comprised of over 20 percent children under 18. Dorchester skims just below Roxbury for second place at 24.2 percent.

For those over 18, the young adult population continues to grow. About 39.4 percent of Boston was adults between 18 and 34 in 2014, up 3 percent from 2014.

Now sitting at the bottom of the list, Dorchester and Mattapan locked down among the lowest percentages of young adults in the city, with 30 percent and 23.6 percent respectively. Though Dorchester contains a staggering 36,166 young adults, their distribution is predictably broader and less concentrated than most other city regions. More university-dense areas like Fenway and Allston/Brighton continue to lead the city in percentage.

Housing is a consistent topic of concern, particularly in terms of the rental market. The report indicates that Boston had 253,749 occupied housing units in 2014, of which 34.9 percent were owner-occupied, “a historically high owner-occupancy rate.”

Dorchester hit 33.8 percent, slightly below the city rate, while Mattapan surpassed it at 38.9 percent. Owner occupancy rates in certain neighborhoods were tracked over the past 35 years in the report, though Dorchester was not among them, showing a steady rise Downtown, a plateauing in Roxbury, and a sharp spike in the past five year on the South Boston Waterfront.
