We estimate the investment gap in the provision of adequate levels of access to airports in Latin America and the Caribbean. Based on georeferenced data for population centers and existing airport locations, we estimate the region requires USD 10 billion in investments to close the gap for 23 million people living in localities of more than 100,000 inhabitants who currently lack sufficient access to airports offering adequate service standards within reasonable travel times. The gap is equivalent to approximately 18% of total investment in transport in Latin America in 2019, but is quite sensitive to variations in the criteria chosen to define access in terms of maximum access time and minimum population center size thresholds.

拉丁美洲和加勒比地区的机场准入差距

我们估计了拉丁美洲和加勒比地区在提供足够水平的机场准入方面的投资缺口。根据人口中心和现有机场位置的地理参考数据，我们估计该地区需要 100 亿美元的投资，才能缩小居住在人口超过 10 万的地区的 2,300 万人的差距，这些地区目前缺乏足够的通道前往提供足够服务标准的机场。合理的出行时间。这一缺口相当于 2019 年拉丁美洲交通总投资的 18% 左右，但对定义通行条件（最长通​​行时间和最小人口中心规模阈值）所选择的标准的变化非常敏感。
