I have written articles in the past, such as this one, stating that cities with populations of over 1 million, especially those with populations over 10 million, have unique challenges and opportunities due to the size of the city, the bureaucracy, and the isolation of people living in areas of concentrated poverty.
I've created concept maps and visualizations that show the planning process and commitment needed by people in every sector and zip code of a city to help close the gaps between rich and poor. Here are a few:
Leadership Commitment. Mentoring Kids To Careers. See map.
Four part strategy. Actions needed to achieve commitment. See here. See description here.
Planning Process. Including building "public will". See explanation.
Throughout this blog, the Tutor/Mentor blog and the Tutor/Mentor Exchange blog, I constantly demonstrate a use of maps to focus attention on were people need the most help, and to support efforts that draw needed resources to each of these areas.
If you live in one of the cities shown on the map above, and you're concerned about the impact of poverty, inequality, youth isolation, etc., I hope you'll take a look at these maps, and browse my Tutor/Mentor Institute, LLC web site and share this with others who have the same concern, and who may already be doing great work to reduce these problems.
People in big cities need to be connecting, building relationships, sharing ideas, and innovating ways to draw resources to their work.
