Setting Up and Working with The Boston Globe Big Picture
The Boston Globe Big Picture is their interactive data visualization and mapping platform. It lets you explore geographic datasets, demographic trends, crime stats, election results, and various other localized data across the Greater Boston area and beyond. The interface is built around layered map views where you can toggle between different data categories and zoom into specific neighborhoods. The main view presents a map of Massachusetts with sidebar controls for dataset selection. Each dataset has its own color scale and legend. You pick a topic from the dropdown, adjust the choropleth or point-layer settings, and then drill down to city, district, or census-tract level. The navigation is straightforward but not immediately intuitive because the control panel hides certain toggles behind collapsed menus. I ran into a specific issue last year when trying to export a high-resolution map for a presentation. The export button produces a fairly low-res PNG by default — good for embedding in an article, useless if you need something printable at 300 DPI. My workaround was to use the browser's print-to-PDF function after enlarging the map to full screen and letting it load all the tile layers completely. That gave me a much cleaner result. It took some trial and error with the viewport size before I found the right zoom level where the PDF came out legible at the resolution I needed.
Another thing people miss: you can layer multiple datasets on top of each other using the comparison mode. Select one dataset as your base layer, then click the plus icon to add a second one. The interface shows both overlays with opacity controls so you can adjust how much you see from each. This is genuinely useful for cross-referencing, like comparing property values against school ratings or transit access against population density. Not everyone finds this feature because the button is small and tucked away. The search function works best when you type the full address or neighborhood name rather than just a street. Partial matches pull up results from outside the Greater Boston area sometimes, which can be confusing if you're not paying attention to the results list. There is a region filter checkbox but it is not highlighted prominently, so I learned to check it manually every time. If you skip that step you might end up looking at data for a town in southern New Hampshire that happens to share a name with one near Boston.
When the tool works well and when it does not
The Boston Globe Big Picture handles most demographic and public-safety datasets reasonably well. Election returns at the precinct level are accurate and update promptly after each election cycle. Housing and development data is solid too, though the update frequency varies by source — some feeds are refreshed quarterly while others lag by months. Where it stumbles is with real-time or near-real-time data. If you are looking for live crime incident mapping, for example, the data here is often a week or two behind what you would find from municipal open-data portals. The Globe prioritizes curated, verified data over speed, which makes sense editorially but can be frustrating if you need current information. For law-enforcement level detail, the official city dashboards will always be more current. Also worth noting: not every municipality in Massachusetts is fully represented. Some smaller towns have sparse or outdated data in the system, usually because the Globe's reporting team did not cover them extensively or the municipal data-sharing agreements are limited. If you are researching a specific town and the dataset looks thin, that is likely the reason and not a technical glitch on your end.
Get the Full Details
The platform itself is free to use. You do not need an account to browse or explore datasets. If you want to save custom map configurations or create personal collections you may need to register, though the basic functionality requires nothing. You can find it at bostonglobe.com/bigpicture or by navigating from the Globe's main site data section. If you are doing serious research beyond casual exploration, I would recommend supplementing this tool with the MassDataPortal or your city's own open data hub. The Globe Big Picture is excellent for seeing the overall picture — and I mean that somewhat literally — but for granular raw data extraction and analysis, going straight to the source is usually faster and gives you more control over what you pull.
