On Sept. 22, 2026, Juneau lost one of its most colorful characters. Musician, lover, iconoclast and social event organizer Carl Scott Fry was better known as the “mayor” of downtown South Franklin.

In Australia, official reporting of health and social measures is predominantly based on administrative data sources where all citizens are asked to volunteer their Indigenous status when completing administrative processes to receive services and programs. Due to historical, sociological and political factors, missing data on Indigenous status is common and varies widely, across many administrative databases. Algorithms and linkage across multiple databases are the primary method used to decrease missingness of Indigenous status in administrative data. We used a capture-recapture approach to quantify the overall missingness of Indigenous status in linked data from the admitted public hospital and emergency department of the regional jurisdiction of the Australian Capital Territory (ACT). We analyzed Indigenous status yearly data (2010–2022). That same approach was used to measure the missingness of Indigenous status by age and sex. Capture-recapture analyses indicated that the hospital and emergency department datasets may not have identified between 35 and 45% of people who are Indigenous over the years of the study period. Our study also found that missingness of Indigenous status was higher for those aged under 45 years and Indigenous males. Our study provides evidence that missingness of Indigenous peoples in administrative data collections in the ACT is significant which has implications for health and social outcome monitoring for Indigenous peoples in the ACT. The capture-recapture method used in this study offers an innovative approach to estimating missingness in administrative databases overall and by different demographic groups.

Huell visits with world famous artist David Hockney in his Los Angeles studio and we get a first hand look at some of the newest work. _Note: This episode was released across Public Broadcasting Service’s (PBS) affiliated stations in California, but not necessarily on the same day for each station. The date shown represents an earliest, approximate airdate for this episode. A more conclusive airdate may potentially be between April 13, 1994 – May 1, 1994. _

The decennial census, mandated by the framers of the Constitution, has evolved along with our nation over the course of their shared history.

The long and winding road has led us to this moment: our final episode. 13 long years will be discussed, dissected and deliberated on this our double stuffed goodbye. Come for the musical numbers, stay for the tears.

Reliable subnational population estimates are essential for applications, yet remain difficult where censuses are sparse, outdated or spatially coarse. Existing population-mapping workflows rely on hand-built geospatial covariates, such as settlement extent, night-time lights, and environmental conditions, which must be assembled and harmonised across scales and geographies. Geospatial foundation models offer an alternative by learning reusable representations of place from more multifaceted and heterogeneous data sources. Here, we benchmark Population Dynamics Foundation Model (PDFM) embeddings against the harmonised geospatial covariates for subnational population estimation in Brazil, Nigeria and the United States. Under geographically structured validation, PDFM increased predictive fit by a median of 20.1% (IQR: 10.0-33.2%, across country-model comparisons) reduction in unexplained variance, and reduced Kullback-Leibler divergence by 23.2% (9.2-26.2%). However, these gains were uneven. PDFM was most advantageous where the geospatial covariates weakly characterised settlement context, such as larger and less-developed subnational areas. Moreover, PDFM performance was scale-coupled with embeddings providing less flexible transfer across spatial aggregations than geospatial covariates. These findings showed that geospatial foundation-model representations of place can improve population estimation in data poor settings, but their benefits break down predictably under spatial scale mismatch, revealing a fundamental limitation of current geospatial AI.

Two weeks after the Trump administration announced a U.S. Forest Service “restructuring” that would close regional offices and most of the agency’s research facilities, impacts to Alaska – home to the two largest U.S. national forests – remain unclear. The U.S. Department of Agriculture announced on March 31 that the Forest Service’s national headquarters will […]
