【解析】

120世纪自70年代初期我国大力推行计划生育政策以来,全国大约少生了约4亿人,人口过快增长的势头得到有效遏制,人口增幅逐渐下降。如图,我国2015年人口总数持续增加,而自2016年自然增长率逐渐降低。但是,由于我国人口基数大,增长快,每年新增人口仍达1000多万,在今后一段较长的时期内,人口总量还将持续增长。故选:C。

2亚洲、非洲和拉丁美洲的一些国家,人口增长过多过快,给社会经济发展造成很大压力,使居民的就业、居住、教育、医疗等问题难以解决,还有一部分国家则长期处于贫困状态,资源使用过度。在欧洲的一些国家,比如意大利、德国和瑞典,近些年来人口一直处于负增长状态,已引起劳动力短缺、人口老龄化等问题。故选:A。

本题考查了我国人口的增长及问题。
