Inside the <counts> container element are the counts of various components of the document in two styles: 1) the predefined counting elements (specific to an element type and shown below) and 2) the generic count element <count> (which is used to count anything that is not one of the predefined, specific types and for which the @count-type attribute names what is being counted).
Best Practice: For counting all of a named element (such as all the figures or all the tables), the specifically-named counting elements (<fig-count>, <table-count>) should always be used. The <count> element should be reserved for 1) counting elements or conditions for which a specifically-named *-count element has not been defined (all footnotes, all contributors, the number of countries of contributors, etc.) or 2) counting only some of a named element or condition. For example, to sub-divide a count into smaller sub-counts, e.g., color figures versus black-and-white figures, use <fig-count> to hold the total number of figures and then use separate <count> elements for the subsets as shown below:
<counts>
  <count count-type="fig-color" count="3"/>
  <count count-type="fig-bw" count="7"/>
  <fig-count count="10"/>
</counts>
Named Counting Elements: The JATS pre-defined named counting elements are:
Is the total number of labeled Figures (see definition of the element <fig>). This is not a count of images or of <graphic> elements. Do not include unlabeled graphics, such as images embedded in table cells, in the count of figures. Also do not make this the count of images inside a figure; for example, if a <fig> contains four panels (a-d) and each panel is a separate image file (4 <graphic>s), the <fig-count> would be “1”, not “4”.
Is the total number of tables (<table-wrap>). Do not include uncaptioned/untitled tables (<array>) in this count. Do not include multiple <table> elements inside a <table-wrap>.
Is the number of display equations (<disp-formula>). Do not include inline equations in this count (<inline-formula>). If you have a display equation that consists of multiple MathML objects, this counts as one equation.
Is the number of bibliographic references within the bibliographic reference list. This may be the number of reference elements (<ref>) or the number of mixed or element citations (for publishers who put multiple <mixed-citation>s or <element-citation>s into a single <ref>). Do not include cases of <mixed-citation> or <element-citation> that appear outside of a <ref-list>.
Is the number of pages in the print or PDF item, including all Roman and Arabic number pages.
Is the number of words in the document.
