"The San Francisco Bay Area, commonly known as the Bay Area, is a populated region that surrounds the San Francisco and San Pablo estuaries in Northern California, United States. The region encompasses the major cities and metropolitan areas of San Francisco, Oakland, and San Jose, along with smaller urban and rural areas. The Bay Area's nine counties are Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. Home to approximately 7.44 million people, the nine-county Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a network of roads, highways, railroads, bridges, tunnels and commuter rail. The combined urban area of San Francisco and San Jose is the second largest in California (after the Greater Los Angeles area), the fifth largest in the United States, and the 56th largest urban area in the world."

This pictorial chart sample shows the population growth by continent in 2010-2013.
"Population growth' refers to the growth in human populations. Global population growth is around 80 million annually, or 1.2% p.a. The global population has grown from 1 billion in 1800 to 7 billion in 2012. It is expected to keep growing to reach 11 billion by the end of the century. Most of the growth occurs in the nations with the most poverty, showing the direct link between high population growth and low standards of living. The nations with high standards of living generally have low or zero rates of population growth. Australia's population growth is around 400,000 annually, or 1.8% p.a., which is nearly double the global average. It is caused mainly by very high immigration of around 200,000 p.a., the highest immigration rate in the world. Australia remains the only nation in the world with both high population growth and high standards of living." [Population growth. Wikipedia]

This onion diagram sample was created on the base of the figure "Social Ecological Model (SEM)" illustrating the webpage "Cultural Competence" from the US Centers for Disease Control and Prevention (CDC) website.
"Why consider cultural competence?
It is important to communicate effectively to both the disparately affected population(s) of interest as well as other key stakeholders at the community, state, and national levels.
The diagram of the Social Ecological Model (SEM) ... depicts how health behaviors of an individual (inner oval) are influenced by the interpersonal, organizational, community, and public policy contexts and environment in which that person exists. Cultural context resides in the interpersonal band, making it a critical consideration when designing any communication plan. All obesity prevention communications should take the culture (e.g., language, thoughts, communications, actions, customs, beliefs, values, and institutions of racial, ethnic, religious, or social groups) of the target population into consideration to be effective. Interventions that successfully achieve this goal demonstrate cultural competence - behaviors, attitudes, and policies that come together in a system, agency, or among professionals to enable people to work effectively in a cross-cultural situation."
