# Global statistics 

This section provides plots and tables summarizing some basic statistics of the RGI 7.0 compared to RGI 6.0. A table comparing the area and number of glaciers per region can be found and downloaded in [](regions/overview).

## Target year

```{card}

Number of glaciers (%) within intervals around the target year 2000 in RGI 6.0 and RGI 7.0.

| Outline year      |   RGI 6.0 (%) |   RGI 7.0 (%) |
|:------------------|--------------:|--------------:|
| 2000 ± 2 years    |          48.9 |          58   |
| 2000 ± 2-5 years  |          15.9 |          18.7 |
| 2000 ± 5-10 years |          27   |          19.5 |
| 2000 ± > 10 years |           8.2 |           3.8 |

```

## Size classes

```{card}

Number of glaciers (N) and percentage of total number per size class in RGI 6.0 and RGI 7.0.

| Area       |   RGI 6.0 (N) |   RGI 6.0 (%) |   RGI 7.0 (N) |   RGI 7.0 (%) |

| > 100 km²  |           962 |           0.4 |           994 |           0.4 |

## Global attributes statistics

```{card} Table: Terminus type statistics

Number of glaciers (N) and area (km²) per terminus type in RGI 7.0 and RGI 6.0. Note that the default designation in RGI 7.0 is now "Not assigned", while in RGI 6.0 lake-terminating glaciers and shelf-terminating glaciers were identified in some regions. The RGI region 19 is entirely labelled as "Not assigned" in RGI 7.0.
