- We're excited to announce major new POI types in Core Places in the
US. We've added nearly 500k apartments and other multi-family housing POIs as premium rows to Core Places, with Geometry for these locations to come in October. We've also added over 500k transit stops - these are point POIs, meaning they are only associated with a centroid and do not come with a polygon geometry.
- Last month SG Places had 8,795,394 points-of-interest (including closed POIs). This month SG Places has 9,946,995 points-of-interest (net +1,151,601 places). These are +1,149,361
CAplaces and -904
- We've added 142 brands (+111 🇺🇸, +33 🇨🇦, +21 🇬🇧) - view the full list here! Below are some highlights:
- Walgreens Pharmacy (
SG_BRAND_33ef43259b465c12) with 9,055 POI
- Bitcoin Depot Bitcoin ATM (
SG_BRAND_81dd9679f8f80f51) with 4,028 POI
- Walmart Auto Care Center (

- +13 Home Health Care Services (621610)
- +13 Financial Transactions Processing, Reserve, and Clearinghouse Activities (522320) - aka brands
- Walgreens Pharmacy (
- We rely on POI metadata to track store openings and closings, and we are especially interested in understanding open/close dates for branded POIs. It can take more than a month to infer open/close dates, so we report brand open/close metrics on a one month delay.
- In this release, we flagged 874 brands with at least one store closure in July 2021, and 1,016 brands with at least one store opening in July 2021.
- Learn more about our open/close columns here.
This month, key changes include:
- +12k Offices of Physicians (621111)
- +10k Pharmacies and Drug Stores (446110)
- Over 525k new point POIs, including transit stops (4851), ATMs (522110, 522320), and EV charging stations (447190). Learn more about these premium rows, which were introduced in the July 2021 Release.
Category Fill Rate -- We monitor category fill rate with 2 metrics: (1) category fill rate across the entire dataset, and (2) category fill rate for branded POI. We want both of these numbers to be 100%.
(1) All POI category fill rate. Last month 99.4%. This month 99.5%.
(2) Branded POI category fill rate. Last month 100.0%. This month 100.0%.
We are ingesting many sources and due to source changes and processing changes, Placekeys do drop over time. In this release, we dropped 19,359 Placekeys (8,667 branded and 10,692 non-branded). Thanks to enhancements to Placekey stability, this is a major improvement from last month, when we dropped nearly 350k. To keep track of the status, predecessors, and latest successor of each Placekey, you can try using the new Lineage API.
- While OWNED polygons are preferred, it does not mean that SHARED polygons are inherently bad. It only means that the exact shape of each POI within the polygon is not discernible, but the general location can be identified by the centroid (
enclosed= FALSE, it indicates that there are reasonable means to derive a unique polygon for the POI (even when
parent_placekeyis not null), and we strive for 100% of branded, non-enclosed POIs to have polygon_class = "OWNED_POLYGON."
- Last month, the percent OWNED polygons for branded, non-enclosed POIs was 78.9%
- This month, the percent OWNED polygons for branded, non-enclosed POIs is 78.2%
- Here is how we're tracking on this metric across releases: OWNED vs SHARED Polygons in SafeGraph Places Release History.
- See the September-2020 release notes for details about the
enclosedcolumn and tweaks to this metric.
- Centroid-Radius Polygons -- We internally track centroid-radius polygons vs precise polygons and strive for 100% precise polygons. You can measure this yourself using the
- Last release, the percent of precise polygons was 96.5%.
- This release, the percent of precise polygons was 96.5%.

- There was a bug affecting the
visitor_home_aggregationcolumn in the Monthly Patterns release for July 2021 and the Weekly Patterns releases for July 19 & 26 and August 2, 9 & 16. This bug caused the
visitor_home_aggregationcolumn to display the same values as the
visitor_home_cbgswas not affected). The bug has been corrected as of the August 23 Weekly Patterns and the September 2021 Monthly Patterns releases.
