That paragraph is based on Humanae Vitae n. 23 and Populorum Progressio, n. 37.
It refers to social problems addressed by governments, problems such as over-population, great differences in wealth/poverty within a population, and various other problems in society, such as broken families, erosion of the family structure, etc.
Humanae Vitae n. 23
Appeal to Public Authorities
- And now We wish to speak to rulers of nations. To you most of all is committed the responsibility of safeguarding the common good. You can contribute so much to the preservation of morals. We beg of you, never allow the morals of your peoples to be undermined. The family is the primary unit in the state; do not tolerate any legislation which would introduce into the family those practices which are opposed to the natural law of God. For there are other ways by which a government can and should solve the population problem—that is to say by enacting laws which will assist families and by educating the people wisely so that the moral law and the freedom of the citizens are both safeguarded.
Seeking True Solutions
We are fully aware of the difficulties confronting the public authorities in this matter, especially in the developing countries. In fact, We had in mind the justifiable anxieties which weigh upon them when We published Our encyclical letter Populorum Progressio. But now We join Our voice to that of Our predecessor John XXIII of venerable memory, and We make Our own his words: “No statement of the problem and no solution to it is acceptable which does violence to man’s essential dignity; those who propose such solutions base them on an utterly materialistic conception of man himself and his life. The only possible solution to this question is one which envisages the social and economic progress both of individuals and of the whole of human society, and which respects and promotes true human values.” (26) No one can, without being grossly unfair, make divine Providence responsible for what clearly seems to be the result of misguided governmental policies, of an insufficient sense of social justice, of a selfish accumulation of material goods, and finally of a culpable failure to undertake those initiatives and responsibilities which would raise the standard of living of peoples and their children. (27) If only all governments which were able would do what some are already doing so nobly, and bestir themselves to renew their efforts and their undertakings! There must be no relaxation in the programs of mutual aid between all the branches of the great human family. Here We believe an almost limitless field lies open for the activities of the great international institutions.

Population Growth
- There is no denying that the accelerated rate of population growth brings many added difficulties to the problems of development where the size of the population grows more rapidly than the quantity of available resources to such a degree that things seem to have reached an impasse. In such circumstances people are inclined to apply drastic remedies to reduce the birth rate.
There is no doubt that public authorities can intervene in this matter, within the bounds of their competence. They can instruct citizens on this subject and adopt appropriate measures, so long as these are in conformity with the dictates of the moral law and the rightful freedom of married couples is preserved completely intact. When the inalienable right of marriage and of procreation is taken away, so is human dignity.
Finally, it is for parents to take a thorough look at the matter and decide upon the number of their children. This is an obligation they take upon themselves, before their children already born, and before the community to which they belong—following the dictates of their own consciences informed by God’s law authentically interpreted, and bolstered by their trust in Him. (39)
