About this dataset

Context

The dataset tabulates the Fairfax city population over the last 20 plus years. It lists the population for each year, along with the year on year change in population, as well as the change in percentage terms for each year. The dataset can be utilized to understand the population change of Fairfax city across the last two decades. For example, using this dataset, we can identify if the population is declining or increasing. If there is a change, when the population peaked, or if it is still growing and has not reached its peak. We can also compare the trend with the overall trend of United States population over the same period of time.

Public facilities are part of the public infrastructure in a well-functioning community environment. The Plan’s Areawide Recommendations for public facilities are based upon the growth projections shown in the Plan. The pace of development is monitored to ensure that the provision of public facilities keeps pace with projected development levels. Components of the public facility plans are reviewed on a periodic basis and revised, as necessary. Generally, the long-range plan for public facilities accommodates population growth as development thresholds are attained. The delivery of approved buildings can occur over many years, necessitating the early identification and acquisition of public facility locations. Commitments for public facilities needed by 2050 should generally be provided as development approvals occur during the first 10 to 20 years of Plan implementation, although facility construction and occupancy will occur in concert with the pace of growth. Staff uses urban models to plan and advocate for public facilities featuring multi-story construction, inclusion of facilities in mixed-use buildings, and shared features such as plazas and parking.

About this dataset

Context

The dataset tabulates the population of Fairfax County by gender across 18 age groups. It lists the male and female population in each age group along with the gender ratio for Fairfax County. The dataset can be utilized to understand the population distribution of Fairfax County by gender and age. For example, using this dataset, we can identify the largest age group for both Men and Women in Fairfax County. Additionally, it can be used to see how the gender ratio changes from birth to senior most age group and male to female ratio across each age group for Fairfax County.
