"Population geography is a division of human geography. It is the study of the ways in which spatial variations in the distribution, composition, migration, and growth of populations are related to the nature of places. Population geography involves demography in a geographical perspective. It focuses on the characteristics of population distributions that change in a spatial context." [Population geography. Wikipedia]
The pictorial chart example "Regional population growth from 2010 to 2016" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Picture Graphs solution from the Graphs and Charts area of ConceptDraw Solution Park.

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."

"At the base of the identity of an organisational is its organizational culture. A culture is comprised of the shared values, customs, traditions, rituals, behaviours and beliefs shared by a social group (national, ethnic, organizational, etc.). Cultures also share languages, or ways of speaking. From a communication perspective, cultures are made and remade through the words we use to describe our world. Culture represents a common set of values (“shared meanings”), shared by members of a population, a organization, a project/ programme purpose unit or a profession (e.g., engineers versus scientists). Culture change with the times but the speed at which the culture of different institutions change varies widely."
