Distribution of employment spatial equity indices in low-rent residential areas in the central urban area of Urumqi.

Employment spatial equity indices for low-rent residential areas and non-low-rent residential areas. (a), EIEOQ; (b), EIEOAW; (c), EIEOA; (d), CIEES. 1st Ring, the first ring core area; 2nd Ring, the second ring area; 3rd Ring, the third ring edge area. The median of all analysis points in each category is represented by a horizontal black line, with the 25th to 75th percentiles indicated by the box. The whiskers represent the minimum and maximum values within 1.5 times the interquartile range, while the points outside this range are considered outliers and are shown as individual markers. The box itself represents the interquartile range, and the whiskers extend to the minimum and maximum values that are not outliers."
